Abstract
High-pressure ac susceptibility and magnetization measurements have been made for the itinerant ferromagnet Cr 48Te 52 up to 8.5 and 17.2 GPa, respectively, to investigate the existence of a pressure-induced magnetic phase transition. The Curie temperature T C (342 K at ambient pressure) decreased with increasing pressure at a rate of −53 K/GPa together with the height of the susceptibility peak associated with the paramagnetic–ferromagnetic transition. On applying pressures of 5–7 GPa, T C decreased to about 70 K, and at pressures above 7 GPa any anomaly was not observed in the temperature dependence of the susceptibility. Magnetization measurements at low magnetic fields showed hysteresis of the M– T curves at low temperature which disappeared at about 7 GPa. These results suggest that the pressure-induced magnetic phase transition occurs at about 7 GPa in Cr 48Te 52.
