Engineers use shaped, shrunken light to switch a material's magnetic state

Engineers at the University of California San Diego have shown that shaped and shrunken light can switch the magnetic states of a material. Published in Nature Communications, the approach could enable faster, smaller and more energy-efficient data storage.

• The method uses shaped and shrunken light to switch magnetic states
• Findings were published in Nature Communications
• The approach could make data storage faster and smaller
• Work was led by engineers at UC San Diego
