The phase equilibria in the ZnGeAs2-CdGeAs2 system were investigated by X-ray, DTA, EDXRF, microstructure observations and SEM. The solid solutions are present in all range of concentrations above 440 C. Below this temperature a deca
Magnetic properties of the new diluted magnetic semiconductor Zn1-xMnxAs2: evidence of MnAs clusters
Laiho,Lisunov,Lahderanta,Zakhvalinskii
, p. 555 - 568 (1999)
The preparation and magnetic properties of the diluted magnetic semiconductor Zn1-xMnxAs2, opening a novel group of II-V2 compounds alloyed with transition metal elements, are reported for the first time. Single crystals of Zn1-xMnxAs2 are obtained with a modified Bridgman method. For x ≤ 0.2 their structure is isomorphic to the ZnAs2 parent compound. Magnetic properties of Zn1-xMnxAs2 are investigated for x = 0.01, 0.05 and 0.1 between T = 2 and 500 K in fields up to 60 kG. All the samples show a steep decrease of magnetization well above 300 K. In low fields (2-200 G) the temperature dependence of the magnetic susceptibility is strongly irreversible below Tb ≈ 250 K. The magnetization displays nonlinear field dependence starting from B approx. 1-2 kG and reaching full saturation above 40 kG. Its temperature dependence is weak between 2 and 300 K. The magnetic properties are explained by the presence of MnAs clusters. The distribution of cluster sizes is described by three overlapping Gaussian functions with the maxima at 1.7, 2.4 and 3.3 nm. At 300 K the corresponding magnetic moments are found to be 1.5, 4.1 and 10.4 in units of 103 μB.
