Studies on the propagation of AC magnetic field through plasma-sprayed superconducting Y1Ba2Cu3O7−x coatings show that complete shielding is achieved up to a certain critical magnetic field strengthH0. Increase in the thickness orJc of the specimen increases theH0 value. Flux-trapping occurs in the specimen at high frequencies and the frequency at which it occurs increases with increase in specimenJc.
