Antiferromagnetic Tetragonal CuMnAs hold promise for future Spintronics and nanoelectronic devices

Researchers from the University of Nottingham are studying a new antiferromagnetic spintronic material - tetragonal CuMnAs. They say that this new material enables new device structure designs that combine Spintronic and nanoelectronic functionality - at room temperature.

An antiferromagnet is a material in which electron spin on adjacent atoms cancel each other out - and so it was considered unsuitable for Spintronics applications. However it was recently discovered that these materials have a physical phenomena that can enable memory and sensing applications.

The researchers are growing the CuMnAs compound one atomic-layer at a time, and they reported that this material shows a number of favorable properties such as high operating temperature and compatibility with common semiconductor materials.
