Lockin to Weak Ferromagnetism in TbNi2B2C and ErNi2B2C
arXiv:cond-mat/0212535 · doi:10.1103/PhysRevB.67.132407
Abstract
This article describes a model in which ferromagnetism necessarily accompanies a spin-density-wave lockin transition in the borocarbide structure provided the commensurate phase wave vector satisfies Q = (m/n)a* with m even and n odd. The results account for the magnetic properties of TbNi2B2C, and are also possibly relevant also for those of ErNi2B2C.
