Abstract

A simple method was developed to obtain high resolution FTIR spectra of powder samples at low temperatures. The method was used to study magnetic ordering in the cuprates R2Cu2O5 and R2BaCuO5 (R -- rare earth or yttrium) related to high-Tc superconductors of the 123 type. Diffuse transmittance spectra due to f-f optical transitions in the intrinsic R3+ ion or Er3+ probe were measured at 2 - 120 K employing BOMEM DA3.002 FT spectrometer.
