Magnetic properties of R2BaNiO5 Haldane spin chains
Source abstract
Abstract
Abstract The magnetic properties of the Ni spin chain compounds R 2 BaNiO 5 (R=Gd, Dy, Yb) were investigated by means of Mossbauer spectroscopy and neutron diffraction . The data provide the size and direction of the R magnetic moments and an estimate of the second order CEF parameters. The T -dependence of sublattice magnetizations are discussed in the context of the “Haldane chain in a staggered field” model (Yokoo et al., Phys. Rev. B 58 (1998) 14424).
