| Open AccessUltrafast all-optical toggle writing of magnetic bits without relying on heat
Toggle switching refers to the switching of magnetization induced by a train of ultrashort laser pulses. The high speed make such switching in extremely promising for devices, however, the underlying toggle switching mechanism in metals is due to heating, and thus has a downside of dissipation. Here, Zalewski et al demonstrate ultrafast ‘cold’ toggle switching, with a mechanism that does not rely on heating in dielectric Cobalt doped Yittrium Iron Garnet.
