Abstract
A magnetic film includes a ferromagnetic layer. The ferromagnetic layer has a thickness or a width in a first direction which is longer than a thickness or a width in another direction, a crystalline structure is a tetragonal structure, and a main vector direction of a c axis of the tetragonal structure is the first direction.
Claims18
A magnetic film comprising:
- a ferromagnetic layer,
- wherein the ferromagnetic layer has a thickness or a width in a first direction which is longer than a thickness or a width in another direction, a crystalline structure is a tetragonal structure, and a main vector direction of a c axis of the tetragonal structure is the first direction, and
- wherein the first direction intersects a thickness direction of the ferromagnetic layer.
A method for manufacturing a magnetic film, the method comprising crystalizing an alloy for which a disorder structure and an order structure are able to be selected while applying a direct-current magnetic field in one direction under a temperature condition equal to or greater than a Curie temperature TCD of the disorder structure and equal to or less than a Curie temperature TCO of the order structure, and
- wherein a direction in which the direct-current magnetic field is applied is a thickness direction of a magnetic film to be stacked.
