Abstract
We report on the first observation of a pronounced reentrant superconductivity phenomenon in a superconductor/ferromagnet layered system. The results were obtained using a superconductor/ferromagnetic-alloy bilayer of . The superconducting transition temperature drops sharply with increasing thickness of the ferromagnetic layer, until complete suppression of superconductivity is observed at . Increasing the layer thickness further, superconductivity reappears at . Our experiments give evidence for the pairing function oscillations associated with a realization of the quasi-one-dimensional Fulde-Ferrell-Larkin-Ovchinnikov-like state in the ferromagnetic layer.
