RT Journal Article T1 Vortex phases in superconducting Nb thin films with periodic pinning A1 Villegas, J. E. A1 González Herrera, Elvira María A1 Sefrioui, Z. A1 Santamaría Sánchez-Barriga, Jacobo A1 Vicent López, José Luis AB Magnetotransport properties have been used to investigate vortex phases in Nb films with periodic arrays of magnetic pinning centers. This kind of samples show a continuous glass transition similar to that observed in Nb plain films, but the periodic pinning yields different critical exponents and enhanced glass transition temperature at the matching field.
