Abstract

Magnetic circular dichroism(MCD) spectra of Gd-Co and Gd-Ni alloys were measured in core excitation regions using evaporated film and arc-melted bulk samples. Antiferromagnetic coupling between spins of rare-earth and transition metals was demonstrated in Gd-Co but it was not the case in bulk Gd-Ni, which gives rise to a possible spin-glass-like state at the liquid nitrogen temperature with the help of hidden ferromagnetic interaction.
