We report here the results of magnetic susceptibility of both n- and p-type superconductors, Nd2-xCexCuO4-y (x=0.14, 0.15, 0.16, and 0.18) and NdBa2Cu3-zZnzO7- (z=0 and 0.02) in the temperature range 2 to 300 K and specific heat measurements on p-type superconductors in the temperature range 5T300 K. Crystal-field (CF) analysis of these results has been performed considering J mixing of the lowest eleven multiplets with intermediate-coupled wave functions. The CF analysis of the magnetic susceptibility data is consistent also with the reported inelastic neutron-scattering spectra. The specific heat data have been accounted for by considering Debye, Einstein, and Schottky contributions. © 1995 The American Physical Society.
