Magnetic Structure of Rare-Earth Nickel Boride-Carbides

Condensed Matter 2008-02-03 v2

Abstract

We present a theory of the magnetic rare-earth nickel boride-carbides (RENi2_2B2_2C, 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. PACS: 74.72.Ny, 75.30.Cr, 75.30.Kz, 75.10.Dg
