Popis: International audience; Modern information technology demands advanced storage material and efficient data writing scheme. Inherent with a superior perpendicular magnetocrystalline anisotropy, the FePt in L1 0 phase envisions magnetic storage with ultrahigh capacity. However, reversing FePt magnetic state and therefore the encoded information has been proven to be extremely difficult. Here, we demonstrate that an electric current is capable to exert a large spin torque on a L1 0 FePt magnet, which ultimately leads to reversible magnetization switching through domain nucleation and expansion in an efficient and simple manner.
