Abstract
A magnetoresistive element includes: a free layer that includes a magnetostrictive layer containing a magnetostrictive material; a pin layer that includes a first ferromagnetic layer; a thin film that is located between the pin layer and the free layer; a piezoelectric substance that is located so as to surround at least a part of the magnetostrictive layer from a direction intersecting with a stacking direction of the free layer and the pin layer and applies a pressure to the magnetostrictive layer; and an electrode that is capable of applying a voltage different from a voltage applied to the free layer and a voltage applied to the pin layer and applies a voltage to the piezoelectric substance so that the piezoelectric substance applies a pressure to the magnetostrictive layer.
