Magnetic properties of REBa2Cu3O7 (RE = Y, Nd, Sm, Eu, Gd, Dy, Ho)

Abstract Magnetic properties of REBa 2 Cu 3 O 7 compounds were studied at low temperatures. The obtained magnetic RE moments are considerably reduced (except for Gd) with respect to free-3+-ion values. These results are ascribed to crystal field effects. The magnetization curves of the superconducting samples exhibit the expected hysteresis behaviour of type-II superconductors.
