  "abstract": "This study reports micro-fabricated magnet and superconductor (permalloy/Pb82Bi18) hybrid film structures sequentially grown by magnetron sputtering and thermal deposition techniques. 300 nm thick PbBi film was quench condensed on top of a patterned permalloy film. Permalloy film was sputtered and patterned to form few micrometer-wide stripes. Ferromagnetic and superconducting layers were separated by Al2O3 insulation. Transport superconducting properties, i.e. transition temperature T-c(H) and second critical field H-C2(T) were measured in a range of applied magnetic field between H=0 and H=7 kOe for the hybrid system and a control sample with only a layer of superconducting film deposited. The H-C2(T) data showed that due to the interplay between the superconducting film and the ferromagnet, superconducting (SC) and normal current paths formed on the SC film. (C) 2015 Elsevier B.V.
