Microwave absorption in a dc magnetic field up to 12 kG, attributed to nonequilibrium contributions to the ac susceptibility, appears at T/sub c/ as the sample is cooled. ESR measurements of Y-Ba-Cu-O show that Cu/sup 2+/ exists only in the fraction of the sample which is not superconducting in a distorted octahedral surrounding.
