Substitutional effects of In by Cu in CeIn2
We have investigated the evolution of the magnetic properties on the Ce(In1−x Cux)2 (0< x ≤ 0.3) series of alloys. The orthorhombic structure of the CeIn2 alloy(Imma)changes into the hexagonal AlB2-type (P6/mmm)for x = 0.05 and, then, into the hexagonal CaIn2-type(P63/mmm)for higher Cu concentrat...

| Summary: | We have investigated the evolution of the magnetic properties on the Ce(In1−x Cux)2 (0< x ≤ 0.3) series of alloys. The orthorhombic structure of the CeIn2 alloy(Imma)changes into the hexagonal AlB2-type (P6/mmm)for x = 0.05 and, then, into the hexagonal CaIn2-type(P63/mmm)for higher Cu concentrations, up to x = 0.3. The dc (ac) magnetic susceptibility shows an abrupt decrease of the magnetic transition temperature from 22K to 5.4K (x = 0.05). The results indicate the influence of the crystallographic type of structure and disorder effects on the magnetic behavior along the series. |
