Bulk single crystals of manganese phosphide (MnP) were grown from melt at 1 GPa and 1200 °C by using a cubic-anvil, high-pressure, and high-temperature technique. The obtained black colored crystals exhibit a plate-like morphology, with flat surfaces and maximum dimensions up to ～4 × 2 × 0.5 mm3. The orthorhombic crystal structure was confirmed by X-ray diffraction [Pnma, 62, Z = 4, a = 5.2510(4) ?, b = 3.1670(3) ?, c = 5.9098 (4) ? and V = 98.279(14) ?3]. Temperature-dependent magnetization measurements reveal the occurrence of two successive transitions: a paramagnetic to ferromagnetic transition at Tc = 290.5 K and the development of a double helimagnetic order at Ts = 44.5 K. Zero-field 31P NMR measurements in the FM and in the screw-spin AFM state show prominent features, which are compared with previous experimental data and theoretical calculations. The relatively large crystals obtained here open up new possibilities for further explorations of this interesting material.

We have investigated the valence-band and conduction-band electronic structure of MnSb and MnP by means of ultraviolet photoemission and inverse-photoemission spectroscopies. The photoemission and inverse-photoemission spectra are qualitatively consistent
Composition and structural perfection of (AIII,Mn)BV and MnBV (A = Ga, In; B = Sb, As, P) nanolayers

, p. 553 - 558 (2012)
We have determined the elemental composition of laser-deposited (Ga,Mn)Sb, (In,Mn)As, MnP, MnAs, and MnSb layers. The InMnAs layers were not single-phase and contained MnAs clusters. Active Ga and Mn diffusion to the substrate and arsenic diffusion from the substrate during the GaMnSb growth process is accompanied by the formation of a GaMnAs intermediate layer.

, p. 36 - 38 (1987)
Spin-waves in MnP have been measured by means of neutron inelastic scattering at various temperatures. Dispersion relation along a-axis exhibits anomalous wave vector and temperature dependences, while the quadratic q dependence was observed along both b and c-axis. The characteristic feature of the spin-wave dispersion relations agree qualitatively with those predicted on analogy with rare earth metals.
Synthesis of MnP Nanocrystals by Treatment of Metal Carbonyl Complexes with Phosphines: A New, Versatile Route to Nanoscale Transition Metal Phosphides
Perera, Susanthri C.,Tsoi, Georgy,Wenger, Lowell E.,Brock, Stephanie L.
, p. 13960 - 13961 (2003)
The reaction of Mn2(CO)10 with P(SiMe3)3 in coordinating solvents at T ≥ 220 °C yields low polydispersity, highly crystalline MnP nanoparticles for the first time. The effect of dimensional limiting has resulted in the stabilization of a ferromagnetic ground state at low temperatures, rather than the metamagnetic state observed in bulk (microcrystalline) MnP. The synthetic methodology reported here is demonstrated to be general for a number of different metals and phosphine sources. Copyright
Synthesis of InP nanofibers from tri(m-tolyl)phosphine: An alternative route to metal phosphide nanostructures

, p. 227 - 233 (2010)
The synthesis of InP nanofibers via a new Ullmann-type reaction of indium nanoparticles with tri(m-tolyl)phosphine (P(PhMe)3) was typically performed to illustrate an alternative route for the preparation of nanostructured metal phosphides, including III-V (13-15) and transition-metal phosphides. Triarlyphosphine compounds such as other two tri(m-tolyl)phosphine isomers, diphenyl(p-tolyl)phosphine, and triphenylphosphine were comparably employed to synthesize InP nanocrystals. From the aspect of the carbonization of triarlyphosphines, Raman spectroscopy and thermo-gravimetric analysis (TGA) investigations of the InP products showed that the stability of these triarlyphosphines conformed to the order of tri(p-tolyl)phosphine ≈ tri(o-tolyl)phosphine 3) 3 (typically see: J. M. Nedeljkovic, O. I. Micic, S. P. Ahrenkiel, A. Miedaner and A. J. Nozik, J. Am. Chem. Soc., 2004, 126, 2632) and P(C8H 17)3 (C. Qian, F. Kim, L. Ma, F. Tsui, P. D. Yang and J. Liu, J. Am. Chem. Soc., 2004, 126, 1195) according to the difference in preparative temperature for phosphide synthesis. Raman and photoluminescence properties of the as-synthesized InP nanocrystals were further studied, and the synthetic mechanism of our method was reasonably investigated by GC-MS analysis. Moreover, the current route was successfully extended to prepare GaP, MnP, CoP and Pd5P2 nanocrystals. The Royal Society of Chemistry 2010.

We synthesized uniform-sized nanorods of transition metal phosphides from the thermal decomposition of continuously delivered metal-phosphine complexes using a syringe pump. MnP nanorods with dimensions of 8 nm × 16 nm and 6 nm × 22 nm sized were synthesized by the thermal decomposition of Mn-TOP complex, which was prepared from the reaction of Mn2(CO)10 and tri-n-octylphosphine (TOP), using a syringe pump with constant injection rates of 10 and 20 mLVh, respectively. When Co-TOP complex, which was prepared from the reaction of cobalt acetylacetonate and TOP, was reacted in a mixture solvent composed of octyl ether and hexadecylamine at 300 °C using a syringe pump, uniform 2.5 nm × 20 nm sized Co2P nanorods were generated. When cobaltocene was employed as a precursor, uniform Co2P nanorods with 5 nm × 15 nm were obtained. When Fe-TOP complex was added to trioctylphosphine oxide (TOPO) at 360 °C using a syringe pump and then allowed to age at 360 °C for 30 min, uniform-sized FeP nanorods with an average dimension of 12 nm × 500 nm were produced. Nickel phosphide (Ni2P) nanorods with 4 nm × 8 nm were synthesized successfully by thermally decomposing the Ni-TOP complex, which was synthesized by reacting acetylacetonate [Ni(acac)2] and TOP. We measured the magnetic properties of these nanorods, and some of the nanorods exhibited different magnetic characteristics compared to the bulk counterparts.
ThMnPnN (Pn = P, As): Synthesis, Structure, and Chemical Pressure Effects

Mn-based ZrCuSiAs-type pnictides ThMnPnN (Pn = P, As) containing PbO-type Th2N2 layers were synthesized. The crystal and magnetic structures are determined using X-ray and neutron powder diffraction. While neutron diffraction indicates a C-type antiferromagnetic state at 300 K, the temperature dependence of the magnetic susceptibility shows cusps at 36 and 52 K respectively for ThMnPN and ThMnAsN. The susceptibility cusps are ascribed to a spontaneous antiferromagnetic-to-antiferromagnetic transition for Mn2+ moments, which is observed for the first time in Mn-based ZrCuSiAs-type compounds. In addition, measurements of the resistivity and specific heat suggest an abnormal increase in the density of states at the Fermi energy. The result is discussed in terms of the internal chemical pressure effect.

The binary transition-metal monophosphides CrP, MnP, FeP, and CoP have been studied with X-ray photoelectron spectroscopy. The shifts in phosphorus 2p 3/2 core line binding energies relative to that of elemental phosphorus indicated that the de
