Newly Identified ‘Universal’ Property of Metamagnets May Lead to Everyday Uses

A new physics discovery made by a University of Virginia-led team may lead to more efficient refrigerators, heat pumps and airport scanners, among many possible uses –perhaps within a decade.

The team of physicists and materials scientists have discovered a universal law governing the magnetic properties of metamagnets – metal alloys that can undergo dramatic increases in magnetization when a small external magnetic field is applied, such as from a permanent magnet or an electromagnet.
