Title: Magnetic property, Raman spectroscopy and crystal field analysis of Sm{sub 3+} in Sm(BrO{sub 3}){sub 3}⋅9H{sub 2}O

Single crystals of Sm(BrO{sub 3}){sub 3}⋅9H{sub 2}O (SmBR) were grown and the principal molar susceptibility perpendicular to c-axis (χ{sub ⊥}) was measured from 300 K down to 14 K and χ{sub ‖}, the parallel susceptibility, anisotropy was measured in the temperature range of 300-120 K. A cross-over between χ{sub ‖} and χ{sub ⊥} was observed at ∼ 120 K i.e., below this temperature χ{sub |||}<χ{sub ‖}. Raman spectra of SmBR were recorded in the wave number range of 10-4000 cm{sup −1} and crystal field (CF) Stark energies were extracted from the spectra. A good theoretical simulation of the observed magnetic susceptibilities and observed CF Stark energies of Sm{sup 3+} in SmBR was achieved using the one electron crystal field (CF) interaction with D{sup 3h} site symmetry. The electronic specific heat along with the quadruple splitting and hyperfine heat capacity were calculated by using the results of CF analysis.
