Abstract
This paper reports the first study of the absorption of an rf electrom agnetic field in high-temperature superconducting samples of YBa2Cu3O7 -x in the range of magnetic fields corresponding to the onset of the ' 'negative trapping'' effect. It is shown how additional annealing and degradation of the sample influence the onset of the effect. A modific ation of the model of dynamic interaction of superconducting loops is used to explain the observed phenomena. (C) 1997 American Institute of Physics.
