(Phys.org) —Interest in oxide-based semiconductor electronics has exploded in recent years, fueled largely by the ability to grow atomically precise layers of various oxide materials. One of the most important materials in this burgeoning field is strontium titanate (SrTiO3), a nominally nonmagnetic wide-bandgap semiconductor, and researchers at Los Alamos National Laboratory have found a way to magnetize this material using light, an effect that persists for hours at a time.
