Abstract
We present experimental evidence of magnetization modification by superconductivity in a ferromagnet/superconductor heterostructure. By monitoring the magnetization as a function of time with a temperature change, we demonstrate that the magnetization of the ferromagnet is reduced when the heterostructure is cooled below the superconducting transition temperature Tc. The magnitude of the reduction increases with lower cooling temperature. Besides, the M(T) curve measured in zero field exhibits irreversibility between cooling and warming branches above Tc. These results can be qualitatively understood in terms of the mutual interactions between ferromagnetism and superconductivity.
