DENVER — A small change in temperature can alter a newly fabricated material’s magnetic properties. It’s a unique feature that holds promise for building more dependable data storage devices. “No magnetic material known to man is known to do this,” said Ivan Schuller, a condensed matter physicist at the University of California, San Diego. He described the material March 3 at a meeting of the American Physical Society.

Schuller’s creation consists of nickel layered atop a vanadium oxide compou...
