Abstract
Magnetization and electrical resistivity measurements have been performed for Ce 2 Fe 17 under high pressures of up to 1.2 GPa and high magnetic fields of up to 17 T. At ambient pressure, two antiferromagnetic phases appear at T N =215 K and T c =125 K with decreasing temperature. A metamagnetic transition from the antiferromagnetic to the forced ferromagnetic state is observed at 4.2 K. The transition field increases with increasing pressure, whereas the saturation magnetization, saturation field and T N decrease. New magnetic phases, which are different from the two antiferromagnetic and forced ferromagnetic phases, are observed under high pressure and high magnetic fields.
