Strain Unlocks Unconventional Magnetism in Ruthenium Dioxide

Researchers saw signs of altermagnetism in thin, strained ruthenium dioxide, previously thought non-magnetic in bulk form. This finding revives the material as a candidate for spintronic devices that could be faster and more energy-efficient than today’s ferromagnet-based electronics. Read more »

Stacking Bits: Layer-Selective Skyrmions Point to 3D Memory

Using element-specific X-rays, researchers discovered skyrmions occupied only alternating layers in a synthetic antiferromagnet, not all layers as expected. The ability to control where and how skyrmion bits form within stacked layers offers a design strategy for 3D memory devices that store more data per volume. Read more »
