Abstract

We have studied the magnetic properties of Ce(Fe1-xCox)2 with x ≤ 0.1 by magnetization measurements under high pressures up to 1.2 GPa. In pure CeFe2, the Curie temperature TC decreases, and the saturation magnetization Ms is suppressed by applying pressure. In Co substitution compounds, the transition temperature TA from the ferromagnetic (FM) to the antiferromagnetic (AFM) states and the metamagnetic transition field Bc increase with increasing pressure, while TC and the magnetization of the spontaneous and field-induced FM states decrease. The obtained results indicate that the AFM state becomes stable by the lattice contraction.
