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