N2 - Magnetic field dependences of the glass-liquid transition temperature (Tg) were studied in YBa2 Cu3 O7-x films containing various types of nanoinclusions. The vortex configuration (entangled or straight) and pinning strength for each vortex are crucial to the behaviors of Tg. c -axis correlated pinning centers optimize these factors and achieve the upper limit of Tg, which is determined by loss of line tension of vortices, if they are elongated through a thickness of a sample. By optimizing pinning centers, critical temperature, and a matching field, a Tg value of 77 K can be obtained in YBa2 Cu3 O7-x in a magnetic field as high as 27 T.
