Abstract

Critical current density (J_c) and irreversibility field (B _irr) were measured for a GdBa₂Cu₃O _7-δ film with gold nanorods which were elongated along the c-axis of the film. The crossover from the single vortex pinning to the plastic pinning region occurred near B_Φ at 10K. The 'peak effect' in the J_c-B characteristics at 50-82K and the kink in the B_irr-T curve (T_irr ≤ 87.4K) were observed near B_Φ(≤ 0.43T), when the magnetic fields were applied parallel to the c-axis of the film. The matching field effects have significant roles to determine the behaviours of the vortices in the REBa₂Cu₃O _7-δ (RE: Y, Gd, Sm, etc) films with correlated pinning centres, like nanorods, regardless of temperature.
