Abstract

The magnetic properties of GdxU1-xCo2 system, investigated in the 4-800 K temperature range and fields up to 70 kOe indicated ferrimagnetic order for x ≥ 0.2. The cobalt magnetic moments, opposite to gadolinium ones and the Curie temperatures decrease with decreasing Gd content. The paramagnetic properties evidence in the high temperature range a Curie-Weiss type behavior and the presence of the effective magnetic moments on Co positions. The paramagnetic behavior of cobalt is analyzed in the spin fluctuations model..
