Description

Parameters of the tensors of the electric field gradient (EFG) created by lattice ions at the rare-earth metal (REM) sites in RBa2Cu3O7 (R is a REM or Y) and La2-xSrxCuO4 (0<x<0.3) have been determined by means of 155Eu(155Gd) emission Moessbauer spectroscopy. The EFG tensors at the REM sites have been calculated in the point charge approximation. The experimental and calculated EFGs are shown to be in good agreement when holes are supposed to be mainly in sublattices of the chain and Cu-O plane oxygen for RBa2Cu3O7 and La2-xSrxCuO4, respectively.
