摘要：
High resolution optical absorption spectra of an intrinsic R3+ ion or Er3+ probe have been measured in cuprates R2Cu2O5 (R = Yb, Ho, Dy) related to high-T(c) superconductors of the 123 type. The magnetic transition temperatures, energies of crystal field levels, splittings of the ground state doublet have been determined. Possible directions of the copper magnetic moments in an ordered state of R2Cu2O5 (R = Y, Tb-Lu) are discussed on the basis of the spectra of an Er3+ probe in them.
