Antiferromagnetic Material – Antiferromagnetism. Researchers at Tohoku University, University of New South Wales (Australia), ETH Zürich (Switzerland), and Diamond Light Source (United Kingdom) successfully demonstrated current-induced switching in a polycrystalline metallic antiferromagnetic heterostructure with high thermal stability. Researchers break magnetic memory speed record, Using economic data to create predictive models of anticipated antimicrobial resistance levels across countries, Metasurface enabled quantum edge detection, New supercluster discovered by astronomers, The evolution of single amyloid fibrils into microcrystals, Searching for invisible axion dark matter with a new multiple-cell cavity haloscope. Both, the storage media and the readout sensors utilize ferromagnetically ordered materials, where all magnetic moments align parallel.

Read more » This type of material can be magnetic at the atomic scale and non-magnetic at the macroscopic scale, and as a result, have a unique combination of properties able to solve the current challenges of information and communication technology (ICT). In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions. Your feedback will go directly to Science X editors. The quest for high throughput intelligent computing paradigms - for big data and artificial intelligence - and the ever-increasing volume of digital information has led to an intensified demand for high-speed and low-power consuming next-generation electronic devices. (b) The experimental results of current-induced switching of AFM/HM PtMn/Pt structure under applied current JPt in the Pt layer. Until now, the motion of electron spin in antiferromagnetic materials has not yet been studied well. This document is subject to copyright. Some antiferromagnetic materials have Néel temperatures at, or even several hundred degrees above, room temperature, but usually these temperatures are lower. Science X Daily and the Weekly Email Newsletter are free features that allow you to receive your favorite sci-tech news updates in your email inbox. 2(d),(e)). The most common applications of this effect involve giant magnetoresistance (GMR) devices. Researchers discovered that the spin configuration of a nanostructured antiferromagnetic material can be affected by the dimensions of features imprinted onto the material. Different materials react to the application of magnetic field differently. "The experimental results from electrical measurements were supplemented by a magnetic X-ray imaging, helping to clarify the reversible nature of switching dynamics localized within nm-sized AFM domains."
