Magnetic lattice dynamics in HoFeO3
Rare-earth orthoferrites RFeO3 represent interesting and important family of magnetic compounds. Their crystal and magnetic structures were studied by the neutron powder diffraction technique several decades ago. Recently, interest to this family has been greatly renewed because of discovery of their multiferroic properties in some compounds of RFeO3 series with R = Dy, Gd and Sm. There is an indication that Dzyaloshinsky-Moria interaction is responsible for the emergence of ferroelectricity in RFeO3 at relatively high temperatures (above Tsr ~ 50-60 K). Therefore, more precise and detailed studies of crystal and magnetic properties of the RFeO3 compounds are essential in complex studies of coupling between the magnetic and ferroelectric order parameters in multiferroic materials. In this regard, knowledge of the magnetic exchange interaction parameters is of great importance. We propose the inelastic neutron scattering measurements on IN12 spectrometer in order to determine the parameters of Heisenberg exchange and Dzyaloshinsky-Moria interactions in single crystal HoFeO3.
