Magnetic lattice dynamics in HoFeO3; continuation at low-energy range
In order to better resolve Ho3+ dispersion in the vicinity of CF line,observed during the previous experiment we plan to make the measurements of the spectrum in two Brillouin zones; with different parity of L Miller indexes, e.g. along [H 0 1] and [H 0 2] centred at Q = (1 0 1) and (1 0 2). As it follows from our simulations, the distribution of the dispersion branches intensities will be different for zones with different L-parity. This will provide more-comprehensive data for fitting procedure and exchange parameter determining. The temperature of measurements: 2.5 K, in the transfer energy range of 0-5 meV. For this purpose we ask for 3 days of beam time on IN12. In order to unambiguously conclude on the magnetic origin of the observed low energy scattering and suppress the incoherent background we propose to use in addition the polarized neutron option of IN12. Thus, we request totally for 5 days (3 unpolarised + 2 polarised) of beam time. This experiment is a part of the PhD thesis of Mr. A. Ovsyanikov in frame of DFG supported project at Institute for Crystallography RWTH Aachen University.
