Abstract:
According to one embodiment, a magnetic memory device includes a conductive layer, a first magnetic layer, a second magnetic layer, and a first nonmagnetic layer. The conductive layer includes first and second regions, and a third region between the first region and the second region. The second magnetic layer is provided between the third region and the first magnetic layer in a first direction crossing a second direction. The second direction is from the first region toward the second region. The first nonmagnetic layer is provided between the first and second magnetic layers. The second region includes first to third conductive portions. A direction from the first conductive portion toward the second conductive portion is aligned with a third direction. The third direction crosses a plane including the first and second directions. The third conductive portion is between the first and second conductive portions in the third direction.
