Abstract
Magnetic susceptibility measurements on YBa2Cu3O7−δ rod materials by an ac balanced bridge technique are made in fields of up to 50 mT and over the temperature range from 4.2 K to just belowT c . A largeH c2 accompanied by characteristic form of hysteresis has been shown. A modified critical state model of Anderson [Phys. Rev. Lett. 9, 309 (1962)] is adapted to fit the curves in the region where hysteresis is dominant because of flux trapping. A conceptual model of structure vortex lattice transition due to the intrinsic pinning of the layering configuration is suggested, which can provide an explanation of the magnetic behaviour of oxide superconductors.
