Abstract:For YBa2Cu3O7−x samples the temperature dependences of the low field microwave absorption spectra as well as of the magnetization curves are investigated and discussed. Combination of these data shows that strong microwave absorption can be observed under conditions excluding the possibility of flux trapping by the sample.
