Flashes of femtosecond laser light, lasting just a few trillionths of a second, have made it possible to observe new magnetic structures for the first time. By using light as a remote control, ...

A team of scientists has developed a powerful new way to detect subtle magnetic signals in common metals like copper, gold, and aluminum—using nothing more than light and a clever technique. Their ...

New research shows that light’s magnetic field is far more influential than scientists once believed. The team found that this magnetic component significantly affects how light rotates as it passes ...
