A tiny squeeze dramatically changes the magnetism of exotic materials

By · Published by Everything Blog

In short

The discovery, detailed in *Physical Review X* and *Advanced Materials*, reveals that mechanical strain directly influences both electron movement and magnetic structures. During laboratory testing, scientists compressed manganese telluride and iron sulfide crystals between titanium plates to measure their responses. Observations confirmed that the pressure modified the materials' anomalous Hall effect and altered the populations of their magnetic domains. These findings provide a practical method for regulating electron transport, which is essential for advancing spintronics.

Scientists at the Department of Energy's Oak Ridge National Laboratory have discovered that applying a small amount of pressure can dramatically alter the magnetic properties of a promising new class of materials called altermagnets. Using neutron experiments, the researchers uncovered how a simple mechanical squeeze can change the way these materials behave, offering a potential new approach to controlling magnetism.

The results, reported in two consecutive studies published in Physical Review X and Advanced Materials, show that mechanical strain can influence both magnetic structures and the movement of electrons. This ability could provide a straightforward way to control materials being investigated for advanced electronic technologies.
