While magnetism is essentially the strongest quantum mechanical phenomenon, modern description of magnetization dynamics relies on thermodynamics and the corresponding approximations. I will show that femtosecond laser pulse is a unique stimulus in magnetism that pushes the magnetization dynamics into a counter-intuitive regime, where the classical approximations fail, heat does not destroy, but reverses magnetization and solely a flash of light writes magnetic bits at the record-breaking speeds.
