Abstract

The temperature dependent zero-field-cooled, field-cooled and remanent moment were measured at various applied magnetic field (from 10 Oe to 4000 Oe) for the YBa2Cu3Oy/PrBa2Cu30y (96Å/48Å) superlattice to investigate the saturated flux pinning. The results showed that MREM = MFC - MZFC as H≤ 195 Oe while MREM > MFC - MZFC as H > 203 Oe. This critical magnetic field (203 Oe in this report) is defined as Hs. Hs will be studied together with the penetration field H* which is obtained from both the magnetic relaxation for various applied magnetic field and the hysteresis curve. It is found that the Hs is closely related to H*. The result are discussed by using the bean's critical state model.
