Abstract

Inelastic neutron scattering data recorded in this work and elsewhere provide a useful set of crystal-field (CF) energy levels for the ground J = 6 term of Ho 3+ in HoFeO 3 . Resolution of the low energy, temperature dependent pseudo-quadrupole ground state splitting and magnon peaks is consistent with self-ordering of the Ho 3+ sub-lattice ordering at T Ho ~ 8 - 10 K and supports earlier electron spin resonance investigations of the Ho 3+ magnon behaviour. Systematic analysis of the grouped singlet CF levels of Ho 3 :HoFeO 3 , in conjunction with the CF Kramers doublet levels of the neighbouring Er 3+ : ErFeO 3 , suggests possible CF parameters for the two systems.
