X-ray nanotomography of a curved magnetic thin film with perpendicular anisotropy reveals curvature-induced modifications in the magnetic configuration.

Curvature Induced Magnetism

August 14th, 2025

A Georgetown University team, led by postdoctoral fellow Dhritiman Bhattacharya and graduate students Colin Langton and Bradley Fugetta, has demonstrated how bending thin magnetic films can change the way the tiny magnetic regions inside them are arranged. Their work provides direct experimental evidence that curvature can induce a “handedness,” or chirality, in magnetic patterns—a finding that could be a game-changer for spintronics, a field that uses electron spin to store and process information.…
