Research Abstract |
In this study I have investigated spin-lattice coupling in new-type multiferroic materials, F_eC_(r2) O_4 and M_(n3) O_4, by using synchrotron X-ray diffraction and neutron diffraction technique. From these experimental results, it was clarified that orbital-degree-of-freedom play important role in large magnetic field response of these materials. I have performed inelastic neutron scattering experiment on multiferroic T_bM_nO_3 to understand electromagnetic excitations observed by terahertz spectroscopy measurements.
