    Abstract

    The irreversibility temperatures were measured for a-axis oriented and c-axis in-plane aligned Y123/Prl23 multilayer films in various magnetic fields. Pr123 layers act as two-dimensional (planer) c-axis correlated artificial pinning centers (APCs) in the multilayer films. In the irreversibility field -temperature curves, the crossover was observed near matching field Bψ for the multilayer films, when the magnetic fields were applied parallel to the c-axis of the film (B//c). It is suggested the vortex state in Y123 films with two-dimensional APCs is Bose glass below the crossover field. The B irr - T curves under B//a shifted toward lower temperature and magnetic field regions.
