Spin-lattice correlation in Eu3+ doped antiferromagnet TmFeO3

We report physical properties of Eu-doped bulk TmFeO3 through x-ray diffraction, magnetic susceptibility (c), Raman scattering and x-ray absorption spectroscopy (XAS) study, which shows similar orthorhombic structure with Pbnm space group as TmFeO3. Magnetic measurement on Eu-doped TmFeO3 provides evidence for spin reorientations of Fe3+. Further, the Raman spectra of Eu3+ doped TmFeO3 show significant changes in Raman modes as a function of temperature which are the evidences for strong spin-lattice interaction. From XAS spectra the L-edge of Fe provides information on valance state of Fe, whereas K-edge of Oxygen shows that the compound has strong influence of the hybridization of O(2p) state with 3d states of Fe.
