We report an inelastic neutron scattering study of candidate multiferroic ErFeO 3 , a compound that has been previously reported to have three different magnetic states and undergoes signatures of Fe 3 + − Er 3 + cooperative coupling. The spectrum at low energy transfer is dominated by excitations of the Er 3 + character, even above the Er 3 + antiferromagnetic ordering temperature of 4.5 K. In addition, a crystalline electric field excitation at 6 meV exhibits additional energy splitting upon cooling through 4.5 K with mode-dependent polarization. This indicates different moment directions for these modes, an interesting consequence of C y ordering of the Er 3 + moments. [ABSTRACT FROM AUTHOR] |
