| contents | Current-induced vortex glass transition in YBa2Cu3Ox thin films M. Acosta C. Acosta Víctor Sosa Física, Astronomía y Matemáticas YBCO thin film vortex glass transition and current voltage characteristics Nonlinear currentvoltage curves were measured in c-oriented YBa2Cu3Ox thin films at zero external magneticfield. We demonstrated that even in this case the vortex glass model can be used to extract from a criticalscaling analysis the indexes z and n. We associated this behavior to the vortex excitations induced by theapplied current. Our results showed that small z and large glass temperature values are related with a wide andinhomogeneous distribution of pinning forces. The broadening of this distribution was caused by a slightgrain misalignment formed during the growth process 2001 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94201204 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
