Abstract
The magnetic susceptibility χ(T) of Zn0.1Cd0.9GeAs2 + n wt % MnAs (n = 10 or 15) ferromagnetic nanocomposites with a Curie temperature TC = 310 K has been measured as a function of temperature in the temperature range 270–350 K, and their resistivity ρ(p), Hall coefficient RH(p), and magnetization M(p) have been measured as functions of pressure near room temperature. The materials have been shown to undergo a pressure-induced ferromagnetic-to-paramagnetic phase transition, accompanied by a semiconductor–metal phase transition, at a hydrostatic pressure p ≈ 3.2 GPa and room temperature.
