摘要

We present an infrared transmission study of Nd sub(2)CuO sub(4) Kramers doublets as a function of temperature and polarization. Lifting of the J identical with 9/2, 11/2, 13/2 and 15/2 Kramers doublets degeneracies of the order of few cm super(-1) is observed which we ascribe to the exchange coupling of the Nd spins to the Cu subsystem. In particular, we show that the doublet splittings data retrace the Nd sub(2)CuO sub(4) spin reorientation transitions and imply that the Nd-Cu coupling is strongly anisotropic. This finding supports a model used earlier to interpret the spin reorientation transitions as well as the spin-wave excitation gap data.
