Abstract
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 C, on pressure was observed, whereas the value of the Neel temperature, T N, remains almost intact up to the highest applied pressure. In the antiferromagnetic phase region (T C<T<T N), a metamagnetic transition occurs, with a rather low value of the critical metamagnetic field (μ0 H C ∼ 50 mT at 15 K). The μ0 H C value increases nearly twice when applying pressure of 0.8 GPa.
