By Shaping and Shrinking Light, Engineers Alter a Material’s Magnetic Properties
Using a specially engineered beam of light from an ultrafast laser, UC San Diego engineers demonstrate a new approach to switch magnetic information in materials without using an external magnetic field. Photos by David Baillot/UC San Diego Jacobs School of Engineering
A new approach that uses light to switch the magnetic states of a material could lead to faster, smaller and more energy-efficient data storage.
Engineers at the University of California San Diego published their findings in Nature Communications.
