Machine learning offers faster, more reliable analysis of Fermi surfaces

Tokyo University of Science
Peer-Reviewed Publication

Interpreting Fermi surface data requires specialized expertise and is vulnerable to noise, creating a bottleneck in materials research. Researchers now demonstrate a machine learning approach that can analyze simulated Fermi surface images of the alloy Co₂MnGa_xGe_1-xand automatically identify compositions where the Fermi surface morphology changes, even in blurred or noisy data. The method reduces the need for manual screening and could accelerate the discovery of advanced electronic materials.

Researchers discover engineered crystal symmetry to power more efficient next-gen magnetic memory device

Science China Press
Peer-Reviewed Publication

A research team led by the Ningbo Institute of Materials Technology and Engineering (NIMTE), CAS, has achieved a breakthrough in spintronics by demonstrating that nonsymmorphic symmetry in hexagonal SrIrO₃ protects topological Dirac semimetal states. This unique electronic structure leads to record-breaking charge-spin conversion efficiency, enabling magnetic switching with ultra-low power dissipation. The study establishes a robust and universal criterion for designing future energy-efficient spintronic devices.
