摘要：
According to one embodiment, a magneto-resistive effect device, includes a stacked body stacked on a substrate, a pair of first electrodes that feeds current to the stacked body, a strain introduction member, and a second electrode for applying a voltage to the strain introduction member. The stacked body includes a first magnetic layer that includes one or more metals selected from the group consisting of iron, cobalt, and nickel, a second magnetic layer stacked on the first magnetic layer, having a composition that is different from the first magnetic layer, and a spacer layer disposed between the first magnetic layer and the second magnetic layer.
