3D Magnetic Topological Structures for Information Storage

Tech ID: 28850 / UC Case 2016-975-0

Abstract

Researchers at the University of California, Davis, have developed a new way to directly create 3-dimensional topological magnetic structures that allows for efficient information storage with potentially low energy dissipation.

Full Description

Current exploration of spin textures with topological characters is largely limited to 2-dimensional nanostructures and bulk materials. Topological spin texture research has yet to take advantage of the topological character of 3-dimensional patterns, particularly at the micro- and nanoscale.

UC Davis researchers have discovered a new way to create 3-dimensional topological magnetic structures that can be used for information storage. Topological structures such as Möbius bands may be utilized for their unique spin configurations, which display interesting topological properties, like magnetic vortices and skyrmions. The method offers a procedure to set the magnetic state into the topological state, allowing 3D arrays of such topological structures to form a magnetic information storage device with low energy dissipation and high stability.
