摘要：

The magnetothermal properties of the Delafossite-type compounds RCuO2, with R = La, Pr, Nd, Eu, and La0.2Gd0.8 are presented. Particular attention is paid to the low-temperature cooperative behavior of this planar triangular system. Frustration is found to exist for the Kramers-ion compounds. For R = La0.2Gd0.8, a spin-glass-like behavior is found.
