High-pressure effect on magnetic phases in PrRu{sub}2Si{sub}2 single crystal

摘要

We report on magnetization and electrical resistivity with respect to temperature, magnetic field and hydrostatic pressure (p) up to 0.9 GPa. Moderate dependence of the Curie temperature, T{sub}C, on pressure was observed, whereas the value of the Neel temperature, T{sub}N, remains almost intact up to the highest applied pressure. In the antiferromagnetic phase region (T{sub}C < T < T{sub}N), a metamagnetic transition occurs, with a rather low value of the critical metamagnetic field (μ{sub}0H{sub}C ～50mT at 15 K). The μ{sub}0H{sub}C value increases nearly twice when applying pressure of 0.8 GPa.
