MAGNETIC-STRUCTURES AND RELATED PROPERTIES OF SOME RARE-EARTH INTERMETALLIC COMPOUNDS, RCU2

The magnetic structures and some relevant bulk magnetic properties of R(Cu, Ni)//2 (R equals Tb, Tb//2Y//1// minus //z, Dy, Ho, Er and Tm) are summarized. Basically, the magnetic structures are antiferromagnetically modulated with propagation vector 1/3a*. For R equals Tb, Dy, Ho the a-axis anisotropy dominates and the structures are longitudinally modulated. For R equals Tm, Er (probably) the b-axis anisotropy dominates and this results in transversely modulated structures. For R equals Tb, Dy the structures are collinear. For R equals Ho, Er, Tm (probably) an incommensurate modulation coexists with the commensurate a*-axis modulation at the lowest temperature.
