Abstract:

Oxygen deficient ErxY1-xBa3Cu26+y (x=1.0, 0.5) compounds are studied by EPR spectroscopy. The EPR spectra reveal the presence of high spin (S>1) paramagnetic centers, dimers and free Cu2+ ions, which appear enhanced in the mixed R phase and suppressed in the single R123 one, consistent with phase separation. © 2000 Elsevier Science B.V.
