Abstract
To increase an output from a magnetoresistive element without using a special magnetic material, provided is a magnetic detection device including a magnetoresistive element including a ferromagnetic reference layer having a fixed magnetization direction, to which a spin wave induction layer is connected, so that the spin wave induction layer injects, into the ferromagnetic reference layer, electrons having spins in a specific direction by a spin electromotive force internally generated.
