Description
Magnetic suspension effect was first observed in samples of YBa2Cu3O7/AgO (Y-123/AgO) composites. Magnetization measurements of these samples show a much larger hysteresis which corresponds to a large critical current density. In addition to the Y-123/AgO composites, recently they also observed similar suspension effect in other RE-123/Ago, where RE stands for rare earth elements. Some samples exhibit even stronger flux pinning than that of Y-123/AgO sample. An interesting observation was that in order to form the composite which exhibits a strong flux trapping effect the sintering temperature depends on the particular RE-123 compound used. In this paper, the authors present the detailed processing conditions for the formation of these RE-123/AgO composites, as well as the magnetization and critical field data
