“…Significant variations of the magnetic ordering are observed as a function of oxygen concentration for various lanthanides, such as Er (Clinton et al 1995, Maletta et al 1990), Dy, and Nd (Clinton et al 1993(Clinton et al , 1995, while in GdBa 2 Cu 3 O 6 + x the oxygen concentration does not appear to affect the nature of the three-dimensional long-range magnetic order or the ordering temperature (~2.2 K) (Chattopadhyay et al 1988b. In ErBa 2 Cu 3 O 6 + x , for example, T N is initially found to decrease with decreasing x, and for x ¦ 0.5 long-range 3D magnetic order occurs below T N and 2D short-range correlations above T N .…”

Several recent examples are used to demonstrate that Raman and infrared spectroscopy can be successfully used as a novel experimental tool to study microscopic processes involving 4f electrons in rare earth (RE) cuprates. Raman-active crystal field (CF) excitations in Nd CuO 2 4 were measured under hydrostatic pressure up to~7 GPa. The observed pressure-induced shifts of the CF levels were interpreted using density-functional-theory-based ab initio calculations and the superposition model. An infrared transmission study of the 4 I J , J = 9/2, 11/2, 13/2 multiplets of Nd 3+ in Nd CuO 2 4 reveals a splitting of the Kramers doublets of the order of a few cm -1 due to the Nd-Cu exchange interaction. This study shows that these splittings can be described by an effective anisotropic exchange Hamiltonian for the Nd 3+ ion expressed in terms of spherical tensor operators up to the sixth order. The isotropic term in the exchange Hamiltonian vanishes for symmetry reasons in this case. An analysis of the infrared transmission spectra in RE 1+x Ba 2-x Cu 3 O 6+d (RE = Nd, Sm) up to~10 000 cm -1 indicates that, besides the regular sites, the RE ions also occupy Ba sites, even in the samples with the cation stoichiometry 1-2-3.
