    Abstract

    The glass-liquid transitions of quantized vortices were studied to understand the vortex behavior in Y Ba2 Cu3 O7-x films. We systematically controlled the pinning strength, spatial distribution, and shape of disorders by engineering of nanoinclusions in Y Ba2 Cu3 O7-x films. In these disorder systems, we observed the crossover between the vortex glass (VG) and the Bose glass (BG). The increase in pinning strength and ordering of isotropic disorders do not change the critical exponents and the conversion between the BG and the VG is triggered only by the anisotropy of pinning centers.
