Angular Dependence of the Flux Pinning For YBa2Cu3Oy/PrBa2Cu3Oy Superlattice
The angular dependence of the magnetic relaxation for YBa2Cu3Oy/PrBa2Cu3Oy (YBCO/PBCO) superlattice was measured under magnetic field to investigate the flux pinning. The applied magnetic field was 0.1 Tesla. The direction of the applied magnetic field makes an angle of 10o,20°,30o,45°... with the c-axis of YBCO/PBCO superlattice. Based on the Anderson-Kim model we derive the pinning energy of this film. The pinning energy is angular independent. The results are discussed.
