Abstract
We describe two new memory effects detected as additional changes in signals of field-modulated microwave absorption of YBa2Cu3O7-delta powders. They appear when the scanning direction of the field is reversed or when the sample is cooled. The observed effects can be attributed to vortex distribution in superconducting YBa2Cu3O7-delta particles. (C) 1997 Elsevier Science Ltd.
