Abstract
A magnetic memory according to an embodiment includes: a magnetic member having a cylindrical form, the magnetic member including a first end portion and a second end portion and extending in a first direction from the first end portion to the second end portion, the first end portion having an end face, which includes a face inclined with respect to a plane perpendicular to the first direction.
Claims36
A magnetic memory comprising:
- a magnetic member having a cylindrical form extending in a first direction along a central axis of the magnetic member and having an inside surface and an outside surface, the magnetic member including a first end portion and a second end portion opposite to the first end portion in the first direction, the first end portion having an end face, which includes a face inclined with respect to a plane perpendicular to the first direction, the face of the end face crossing the outside surface and the inside surface;
- a nonmagnetic insulating material extending in the first direction, and being provided in the cylindrical form of the magnetic member and being surrounded by the inside surface of the first end portion;
- a first electrode electrically connected to the first end portion;
- and
- a second electrode electrically connected to the second end portion.
