Temperature ‘lock’ for new hard drives?

Scientists can alter a new material’s magnetism by varying its temperature

DENVER — A small change in temperature can alter a new material’s magnetic properties. It’s a unique feature. “No magnetic material known to man is known to do this,” reports Ivan Schuller. The physicist works at the University of California, San Diego. He described his team’s discovery here on March 3, at a meeting of the American Physical Society.

 

Schuller envisions this material as the basis of a new generation of hard drives. They would store data to be used by computers. Such a new devic...
