N. Senthilkumaran et al., MAGNETIC-SUSCEPTIBILITIES AND CRYSTALLINE ELECTRIC-FIELD EFFECTS IN SINGLE-CRYSTALS OF NDBA2CU3O7-DELTA, Physica. B, Condensed matter, 224(1-4), 1996, pp. 565-567
We report the directional magnetic susceptibilities on single crystals
of NdBa2Cu3O7-delta. Crystal field (CF) analysis considering orthorho
mbic symmetry at the Nd3+ site has been performed and a best set of CF
parameters have been obtained. The energy levels obtained from the pr
esent fit are in good agreement with the inelastic neutron scattering
spectra.
