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 YBa2Cu3O7−x in a magnetic field as high as 27 T.}, pages = {092504-1--092504-4}, title = {Control of the glass-liquid transition temperature in YBa2Cu3O7-x films}, volume = {79}, year = {2009}, yomi = {ホリデ, トモヤ and マツモト, カナメ} }
