Book excerpt: We report the results of an experimental study of a persistent coil made out of YBa2Cu3O7 coated conductors. The magnitude of the persistent current and the rate of decay were investigated. Two distinct modes of relaxation are evident -- one is flux creep and the other, which is much faster, is of less obvious origin. Our conclusion is that the persistent current in such a coil can be large enough and decay slowly enough so that coated conductors can be used to make persistent coils for a variety of applications.
