摘要

研究了RCoGaO4 (R = Lu, Yb)层状钴酸盐单晶的磁性能和磁热效应。YbCoGaO4晶体磁化率的强各向异性证实了它的Ising自旋玻璃行为，而在LuCoGaO4晶体中观察到类海森堡自旋玻璃相。

Magnetocaloric effect in single crystals of RCoGaO4 (R = Lu, Yb) layered cobaltites

The magnetic properties and magnetocaloric effect of single crystals RCoGaO4 (R = Lu, Yb) layered cobaltites were investigated. The strong anisotropy of magnetic susceptibility for YbCoGaO4 crystal confirms its Ising spin glass behavior while in LuCoGaO4 crystal Heisenberg-like spin glass phase is observed.
