Hidden Magnetic Structures Revealed Physics 14, s31 Researchers capture the previously hidden twists of spins in the domain wall of a “proper” antiferromagnetic material, chromium oxide. M. Wörnle/ETH Zurich × “Interesting but useless,” is how Louis Néel famously described antiferromagnets, materials for whose discovery he was awarded the 1970 Nobel Prize in physics. Jump forward 50 years and these materials are trending among condensed-matter physicists, who are exploring their use in next-generation information-processing and storage devices. But to take the step from useless to useful, many unknowns still need to be uncovered. Now Martin Wörnle and his colleagues at the Swiss Federal Institute of Technology (ETH) in Zurich resolve one of those mysteries: how the spins in a “proper” antiferromagnetic material one where the spins can only point either up or down twist between domains [1].
