Model combinatorial films (CFs) which host a pure superconductor adjacent toa ferromagneticsuperconducting hybrid film (HF) are manufactured for the studyof the influence of ferromagnetic nanoparticles (FNs) on the nucleation ofsuperconductivity. Careful resistance measurements were performedsimultaneously on two different sites of the CFs. Enhancement ofsuperconductivity and magnetic memory effects were observed only on the hybridsite of the CFs but were absent on their purely superconducting part. Ourresults give direct proof that the FNs modulate the superconducting orderparameter in an efficient and controlled way giving us the possibility ofmiscellaneous practical applications.
