Pressure-induced metamagnetic transition in the Cd0.7Mn0.3GeAs2 ferromagnetic semiconductor

  • 37 Accesses

The magnetic susceptibility χ/χ0 and the longitudinal Δρ zz 0 and transverse Δρ xx 0 magnetoresistances have been measured as functions of the hydrostatic pressure P ≤ 7 GPa at room temperature in the high-temperature ferromagnetic semiconductor Cd0.7Mn0.3GeAs2 with a chalcopyrite structure and the Curie temperature T c = 355 K. A pressure-induced metamagnetic transition from the low-magnetization state to the high-magnetization state has been observed in Cd0.7Mn0.3GeAs2 near the magnetic ordering temperature. This transition is accompanied by the hysteresis of the magnetic susceptibility and magnetoresistance.
