摘要
According to one embodiment, a magnetoresistance effect element includes first and second shields, first and second side magnetic units, a stacked body, and a hard bias unit. The first side magnetic unit includes a first soft magnetic layer, a first nonmagnetic intermediate layer, and a second soft magnetic layer. The second side magnetic unit includes a third soft magnetic layer, a second nonmagnetic intermediate layer, and a fourth soft magnetic layer. The stacked body includes a fifth ferromagnetic layer, a third nonmagnetic intermediate layer, and a sixth ferromagnetic layer. The hard bias unit is provided between the first and second shields. A first distance between the first and fifth magnetic layers is shorter than a second distance between the second and sixth magnetic layers. A third distance between the third and fifth magnetic layers is shorter than a fourth distance between the fourth and sixth magnetic layers.
