    摘要： According to one embodiment, a magnetic element includes a first member and a first magnetic portion. The first member includes a first region, a second region, and a third region positioned between the first region and the second region in a first direction. The first region includes at least one first element selected from the group consisting of Au, Ir, Al, Ta, TaN, W, Hf, Pt, and Pd. The second region includes at least one second element selected from the group. The third region includes at least one third element selected from the group. A concentration of the third element in the third region is lower than a concentration of the first element in the first region and lower than a concentration of the second element in the second region. A direction from the first region toward the first magnetic portion is aligned with a second direction.

    摘要： According to the embodiment, a magnetic memory device includes a magnetic body. The magnetic body includes first and second extending regions, and a first connecting region. The first extending region spreads along a first direction and along a second direction crossing the first direction, and includes first and second end portions extending in the first direction. The second end portion is separated from the first end portion in the second direction. The second extending region spreads along the first direction and along a third direction crossing the first direction, and includes third and fourth end portions extending in the first direction. The fourth end portion is separated from the third end portion in the third direction. The first connecting region is provided between the first and third end portions, and connects the first end portion with the third end portion.

    摘要： A magnetic storage device of an embodiment includes: a first magnetic part including a first portion and a second portion and extending in a first direction from the first portion to the second portion; a layered part which is stacked on the first magnetic part in a second direction intersecting with the first direction; a first electrode electrically connected with the first portion; and a second electrode electrically connected with the second portion. The layered part includes a first layer and a second layer which is disposed between the first layer and the first magnetic part, the second layer includes a metal oxide, and the first layer includes at least one selected from the group consisting of a metal nitride and a metal carbide.
