dc.description.abstractThe orthoferrites, RFeO3 (R = rare earth), are promising candidates for innovative spintronic applications. HoFeO3 is of particular interest because optical measurements indicate that the magnetic splitting of the Ho3+ ion’s crystal field (CF) ground state lies in the range of antiferromagnetic–resonance frequencies for the Fe subsystem [1]. Inelastic neutron scattering data recorded on the Australian Neutron Beam Centre’s PELICAN time-of-flight spectrometer are consistent with Ho3+ CF levels at about 10.5, 15.4 and 22.0 meV. Additional low energy transitions (< 1 meV) exhibit behaviour that groups into three distinct temperature ranges (Fig. 1). Given that the Fe sub-lattice undergoes magnetic reorientation over the temperature range of 35 K to 60 K, it is believed that these excitations are associated with magnetic splitting of the Ho3+ ground CF level due to an exchange field originating from the Fe sub-lattice.en_AU
