INFLUENCE OF PRESSURE ON MAGNETIZATION OF (CD1-X-YZNYMNX)(3)AS-2

The influence of hydrostatic pressure up to 0.6 GPa on magnetization of (Cd1-x-yZnyMnx)(3)As-2 with various compositions was studied at 4.2 K and in magnetic fields up to 7 T. The obtained experimental data were analysed within our generalized pair approximation model, treating the total Mn-Mn interaction strength as a sum of superexchange and the Bloembergen-Rowland exchange. As a result, we obtained satisfactory agreement between our approach and experiment by introducing a pressure dependence of p-d hybridization potential V-pd in the form V-pd proportional to d(-4), where d is the Mn-As bond length which decreases with pressure.
