Comprehensive Inelastic Neutron Scattering Study of the Multiferroic Mn1-xCoxWO4



Jinchen Wang, R. S. Fishman, Yiming Qiu, J. A. Fernandez-Baca, Georg Ehlers, K.-C. Liang, Yaqi Wang, Bernd Lorenz, C. W. Chu, Feng Ye


Using high-resolution inelastic neutron scattering, we examine the spin dynamics of Mn1-xCoxWO4 in the collinear AF1, the ac-b spiral AF2, and the ac spiral AF5 phases. The spin wave excitations are well described by a Heisenberg model with competing long-range exchange interactions (Ji up to 12th nearest-neighbors) and the single-ion anisotropy K induced by the spin-orbit interaction. While the exchange constants are relatively unchanged, the dominant effect of doping is to change the single-ion anisotropy from easy axis (K>0) in the collinear AF1 phase to easy plane (K<0) in the two multiferroic phases.
