- Аннотация: We study a magnetization reversal by an electric current pulse in a superconductor/insulating ferromagnet/superconductor Josephson junction placed on top of a three-dimensional topological insulator. It is demonstrated that such a system is perspective for low-dissipative spintronics because of the strong spin-momentum locking in the topological insulator surface states. This property provides an ideally strong coupling between the orbital and spin degrees of freedom, thus giving a possibility of efficient reversal of the magnetic moment by current pulse with amplitude lower than the critical current. This results in strongly reduced energy dissipation. The underlying physical mechanism of the reversal is discussed. The influence of the magnetic anisotropy on the controllability of the reversal by the pulse duration is investigated. In addition, a way of a simultaneous electrical detection of the reversal is proposed.
