Abstract

The crystalline electric field (CEF) splitting of the ER³⁺ 4f-shell in the high-T_c superconductor ErBa₂Cu₃O₇ doped with Zn and Ni has been investigated by the inelastic neutron scattering tecnique. the observed exhibit a large number of well resolved CEF transitions between 8 and 80 meV, so that we have been able to determine all nine CEF parameters required for the orthorhombic symmetry. The results are used to derive information on the effective charge associated with the superconducting CuO₂ planes.
