Crystallographic, magnetic and magnetocaloric properties in Yb-based alloy

The crystallographic and magnetic properties as well as the magnetocaloric effect (MCE) of the polycrystalline Yb0.5Gd0.5Ni5 alloy were investigated. The alloy crystallizes in the hexagonal CaCu5 structure. The magnetic properties showed the transition to a ferromagnetic state at Tc = 21.8 K. The he...
