Abstract: We report experiments on a superconducting spin switch based ontechnologically relevant materials as elemental ferromagnetic Co and elementalsuperconducting Nb. The Co-Nb-Co structure exhibits inverse spin switch effect,can be operated at liquid helium temperature and can switch fromsuperconductive to normal state in rather weak applied magnetic fields.Relevant critical currents as a function of temperature and magnetic field aswell as preparation of superconductive or resistive state are addressed here.
