Topics: Applied Physics, Lasers, Magnetism, Materials Science, Phonons When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10–15 seconds). The spin, or angular momentum, of the electrons in the material, thus disappears almost instantly. Yet all that angular momentum cannot simply be lost. It must be conservedContinue reading “Getting Back Mojo…”
