Abstract

The crystalline electric field (CEF) splitting of the Er³⁺ 4f-shell in the high-T_c superconductor ErBa₂Cu₃O₇ doped with Zn and Ni as well as disordered by fast neutron irradiation has been studied by the inelastic neutron scattering technique. The results are used to derive information on the effective charge associated with the superconducting CuO₂ planes and support the idea of magnetic fluctuations to be the mechanism leading to the formation of a superconducting state.
