We have recently reported our results on magnetic susceptibility and microwave absorption studies on Bi2Sr2Ca1−xGdxCu2Oy and Bi2Sr2Ca1−xYxCu2Oy. In the present work two important observations of these investigation, viz, the dependence ofTc on Gdconcentration and the absence of EPR-signals of Gd and Cu, are considered in greater detail. It is suggested that the microwave absorption by fluxon lattice might be playing one of the important and effective pathways for electron spin relaxation resulting in nonobservation of EPR signals.
