Abstract
We report the results of magnetic susceptibility measurements on Ba2YCu3O7-x with various oxygen content (0.1≤x≤0.82) in the temperature range between 78 and 500 K. No sign of long-range magnetic order was observed for any oxygen content. With increasing oxygen defect concentration, x, from 0.1 to 0.82, the Pauli susceptibility gradually decreases from 7×10-4 emu/mol f.u. to half, while a Curie-Weiss-like contribution increases significantly. We ascribe this contribution to the effect of electron localization caused by the random distribution of oxygen defects.Keywords
