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.engjournal articlehttp://dx.doi.org/10.1103/PhysRevB.72.174512https://journals.aps.orgopen access538.9Glass PhaseBose-GlassLatticesDisorderFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
