, p. 826 - 829 (2006)
The electrical resistivity and Hall coefficient of Cd1-x Mn xGeP2 (x=0-0.19) have been measured at 300 K and hydrostatic pressures of up to 5 GPa. The results indicate that CdGeP 2 dissociates to CdP2 and Ge at p = 3.2 GPa, while the incorporation of manganese stabilizes the crystal structure of CdGeP 2, and Cd0.81Mn0.19GeP2 undergoes a reversible phase transition at p = 3.5 GPa.

Charge and magnetization transport in Cd0.81mn 0.19GeP2 dilute magnetic semiconductor under high pressures
Mollaev,Kamilov,Arslanov,Novotortsev,Marenkin,Trukhan,Arslanov,Zalibekov,Fedorchenkob
, p. 987 - 990 (2012)
Cd0.81Mn0.19GeP2 dilute magnetic semiconductor (DMS) has been subjected to a complex study of electric and magnetic properties under high hydrostatic pressures of up to 7 GPa with pressure rise and release. Electrical resistivity, Hall factor, transverse magnetoresistance, relative magnetic susceptibility, and volume magnetostriction have been measured. Compressibility (k) and spontaneous magnetization coeffi-cient (ωS) have been calculated. Pleiades Publishing, Ltd., 2012.
Structural models for covalent non-oxidic glasses. Atomic distribution and local order in glassy CdGeP2 studied by 31P and 113Cd MAS and spin-echo and 31P-113Cd spin-echo double resonance NMR spectroscopy

The structure of glassy CdGeP2 is discussed on the basis of complementary solid-state NMR experiments, including 31P and 113Cd magic-angle spinning (MAS) and spin-echo techniques, as well as 31P-113Cd spin-echo double resonance (SEDOR) NMR. Modeling of the dipolar interactions in conjunction with experimental studies on the crystalline model compounds CdP2 and CdGeP2 reveals the short-range order present in crystalline CdGeP2 is not preserved upon verification. In contrast to the crystalline analogue, glassy CdGeP2 contains a substantial fraction of phosphorus-phosphorus bonds which can be quantitated by means of 31P spin-echo decay data. The analysis reveals that the number of P-P bonds amounts to 55 ± 5% of that expected for a completely random distribution of atoms. The 113Cd-31P SEDOR results are qualitatively consistent with this conclusion but suggest a more complete randomization of the Cd atoms. As a consequence of this randomization of atomic occupancies, the number of Cd-P bonds is significantly reduced in the glassy state. The study provides important experimental data for the development of realistic atomic distribution models for covalent non-oxidic glasses.
