As clusters of reversed domains appear in the FM layer, the SC film shows a percolative behavior that depends on two independent processes: the arrangement of initial reversed domains and the fractal geometry of expanding clusters. For a full labyrinth structure, the behavior of the upper critical field is typical of confined superconductivity on a fractal network.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttp://dx.doi.org/10.1088/1367-2630/15/10/103025http://iopscience.iop.orgopen access538.9Superconducting propertiesTemperature-dependenceMixed-stateThin-filmsDimensionalityAnisotropyExponentsNetworksFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
