- Opis:
- The influence of hydrostatic pressure up to 0.6 GPa on magnetization of (Cd$\text{}_{1-x-y}$Zn$\text{}_{y}$Mn$\text{}_{x}$)$\text{}_{3}$As$\text{}_{2}$ 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$\text{}_{pd}$ in the form V$\text{}_{pd}$ ∝ d$\text{}^{-4}$, where d is the Mn-As bond length which decreases with pressure.
