Scientists Find Metallic Magnet with Largest Yet Atomic Displacement During Thermal Expansion

Alexander Barcza from the University of Cambridge and coauthors from ISIS and Imperial College London in the UK observed the giant magnetoelastic interactions in the material CoMnSi, which is a metallic antiferromagnet. The scientists also discovered that this magnet uses a new mechanism for achieving the large magnetoelastic effects, which involves competing exchange interactions among atoms.
