摘要：

High resolution optical absorption spectra of the ion Er3+ (intrinsic or introduced as a probe) have been measured in cuprates R2Cu2O5 (R = Er, Lu, Y, Tb, Tm) related to high-T(c) superconductors RBa2Cu3O7-x. Er3+ ground doublet splittings, magnetic transition temperatures, energies of crystal field levels for the ground multiplet of R have been determined. Splittings of spectral lines remain also at T > T(N) due to short-range order indicating the low-dimensional character of the copper magnetic lattice.
