摘要:
Provided is a magnetic field shield sheet for a digitizer, which blocks an effect of a magnetic field generated from various components of a main body of the portable terminal device and at the same time improves the sensitivity of an electronic pen when a digitizer feature is implemented in the portable terminal device, while minimizing an influence upon a geomagnetic sensor. The magnetic field shield sheet includes: at least one layer thin magnetic sheet made of a nanocrystalline alloy and flake-treated so as to be separated into a plurality of fine pieces; a protective film that is adhered on one surface of the thin magnetic sheet via a first adhesive layer provided on one side of the protective film; and a double-sided tape that is adhered on the other surface of the thin magnetic sheet via a second adhesive layer provided on one side of the double-sided adhesive tape.

A magnetic stack having a free layer having a switchable magnetization orientation, a reference layer having a pinned magnetization orientation, and a barrier layer therebetween. The stack includes an annular antiferromagnetic pinning layer electrically isolated from the free layer and in physical contact with the reference layer. In some embodiments, the reference layer is larger than the free layer.

The present invention provides a mesoscopic magnetic body comprising a tabular ferromagnetic body whose planar shape has an axis of symmetry, but which is not symmetric in the direction perpendicular to the axis of symmetry, and wherein the magnetic body shows a circular single domain structure upon removal of the external parallel magnetic field. MRAMs which apply such a mesoscopic magnet and production methods thereof are also provided. As a result, it is possible to control the magnetization direction in nano-scale mesoscopic magnets as well as eliminate the limitation on the number of times in rewriting and writing.

摘要:
The present invention provided a method for manufacturing an organic-inorganic composite magnetic material which has organic radical molecules chemisorbed on the surface of a metal substance and exhibits super-paramagnetism or ferromagnetism. An ionic salt of a metal allowing thiol to be absorbed thereon is reduced with a reducing agent in the presence of a stabilizing ligand so as to form a soluble metal particle. The stabilizing ligand absorbed on the formed soluble metal particle is exchanged with a thiol-substituted organic radical having an unpaired electron so as to synthesize an organic-radical absorbed metal particle.
