Abstract
The magnetic properties of a Fe 2P-type intermetallic compound MnRhAs have been investigated under high pressure up to 8.0 GPa by AC susceptibility measurement. Initially, both the antiferromagnetic (AF(I)) to the canted state magnetic transition temperature T t and the canted state to another antiferromagnetic one (AF(II)) transition temperature T C increase with compression. At 4.0 GPa, however, T t decreases abruptly, while the increasing rate of T C becomes larger above this pressure. A pressure-induced magnetic phase transition was seen at around this pressure when T t and T C are plotted in the pressure–temperature phase diagram. The transition from the antiferromagnetic to the ferromagnetic state observed below 160 K with increasing pressure is not frequently observed.
