Probing Anomalous Inelastic Scattering in Spin-ice Ho2Ti2O7 through Resonant Raman Spectroscopy
Abstract
We report on a study of the inelastic scattering properties of (001) and (111) Ho2Ti2O7 single crystals at room temperature. Structural and compositional analysis along with absorption measurement confirms single crystalline phase of all samples. Room temperature polarized Raman measurements were performed on crystals in non-resonant and two different resonant conditions by using six different laser excitation lines. Lorentzian model fitting analysis is performed on all measured spectra in order to identify the difference in the Raman scattering cross-section in resonant and non-resonant conditions. Variations in the fitting parameters on account of different polarization configurations and crystallographic orientations has helped identifying their symmetry if present. Several possible scattering pathways are discussed in order to qualitatively explain the anomalous scattering results in Ho2Ti2O7
