Abstract

The effect of the transverse ac magnetic field on the relaxation process in YBa2Cu3Ox melt-textured superconductors was studied. A factor of 50 suppression of the relaxation rate could be achieved at the expense of some reduction in the maximum trapped field, with the magnetic-induction gradient being unchanged. This phenomenon is interpreted as a result of an increase of the pinning force after the action of the transverse ac magnetic field that is confirmed by the measurement of the trapped-induction distribution.
