One of us, E.M.G., wants to thank the Spanish Ministerio de Educación y Ciencia for a “Ramón y Cajal” contract. 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.
