概要 (Ce$_{x}$Gd$_{1-x}$)Ni is an interesting material to study the magnetic properties of Ce 4$f$ electrons under the strong influence of other magnetic elements. Previous soft X-ray magnetic circular dichroism (XMCD) study of Ce$_{0.2}$Gd$_{0.8}$Ni at the Gd $M_{4,5}$, Ni $L_{2,3}$, and Ce $M_{4,5}$ absorption edges has revealed that, while the Gd 4$f$ and Ni 3$d$ magnetic moments show a saturation at around 2 T, the Ce 4$f$ magnetic moment takes a maximum at around 2 T and then shows a linear decrease with magnetic, which can be interpreted as a spin flip behavior. Present study provides the results of similar XMCD study for Ce$_{0.5}$Gd$_{0.5}$Ni to investigate the stoichiometry dependence of the magnetic properties of Gd 4$f$, Ni 3$d$, and Ce 4$f$ electrons, especially focusing on the spin flip behavior of Ce 4$f$ electrons.
