Magnetic Structure of Rare-Earth Nickel Boride-Carbides
Abstract
We present a theory of the magnetic rare-earth nickel boride-carbides (RENi$_2$B$_2$C, RE=Ho, Er, Tm). Large total angular momentum allows one to employ semiclassical approximation and reduce the problem to the four-positional clock model. The latter gives a proper phase diagram in magnetic field-magnetic moment plane for varying directions of in-plane magnetic field. The theory explains recent experimental observations.
