| Frequency dependence of χ"(T), different position of a maximum in χ"(T) for different crystal orientations, hysteretic behavior between magnetization measurements in zero-field cooling and field coolding regime are attributed to strong magneto-crystalline anisotropy of PrNi ferromagnetic single crystal with TC=20.5 K, which is driven by crystal field effect. Applied pressure shifts TC to higher temperatures (dTC/dp=1 K/GPa). Susceptibility follows the Curie-Weiss law except for b-axis, which is hard magnetic axis. An anisotropic behavior was seen in resistivity measurements with the largest difference between b-axis and c-axis. Resistivity below TC can be described by power law with ρ ∼T2.24 and is field dependent with a positive magnetoresistance. |
