| Description | Journal: Journal of Physics C: Solid State Physics Measurements of the magnetic susceptibilities and their anisotropy between 300 and 26K on single crystals of trigonal neodymium diglycollate are reported here for the first time. The crystal field analysis using intermediate coupling formalism under $D_{3}$ site symmetry was made to explain the observed data and to find out the appropriate energy levels of the ground term. The crystal field parameters thus obtained were B_{2}$^{0}$=-73.0 $cm^{-1}$, B_{4}$^{0}$=-50.0 $cm^{-1}$, B_{4}$^{3}$=-2125.0 $cm^{-1}$, B_{6}$^{0}$=20.0 $cm^{-1}$, B_{6}$^{3}$=1200.0 $cm^{-1}$ and B_{6}$^{6}$=400.0 $cm^{-1}$. Most of the optical levels of excited terms observed from previous optical study were fitted. The g-values corresponding to the lowest level were g/sub ///=0.381, $g_{perpendicular to }$=0.709. Considering the ground term crystal field energy pattern, the Schottky contribution of specific heat was computed at different temperatures. No experiments on specific heat and g-values on this sample have been reported as yet for comparison. From magnetic anisotropy measurements, a second-order reversible phase change was observed below 74K associated with a possible rotation of magnetic susceptibility tensors about the symmetry axis but retaining the overall threefold symmetry. |
