Abstract

Electron paramagnetic resonance (EPR) at 9.25 GHz of Y1-xGdxBa2Cu3O6.02 (0.001 <x <0.05) powder magnetically a ligned along the crystallographic c-direction shows a well resolved Gd3+ fine structure. The crystalline field parameters are determined and their temperature dependence discussed. Due to the special symmetry the exchange interaction between Gd3+ and antiferromagnetic CuO2 layers is small, contrary to Y2-uGduBaCuO5 where Gd3+ and Cu2+ magnetizations are strongly coupled. EPP serves as a probe for internal fields HI at the Gd sites; in Y0.99Gd0.01Ba2Cu2.97Fe0.03O6.02HI
