Magnetic nanostructure control via 바카라 시스템 배팅 torque

바카라 시스템 배팅 is a genuine quantum degree of freedom that does not have classical correspondence. In ferromagnets, the 바카라 시스템 배팅-바카라 시스템 배팅 exchange interaction can have sizable magnitude (~ eV) and thus magnetic ordering can be in principle manipulated by using this exchange interaction. For instance, when 바카라 시스템 배팅-polarized currents are injected into ferromagnets and if the 바카라 시스템 배팅 polarization direction of the currents differs from the magnetization direction of the ferromagnet, the exchange interaction induces magnetization dynamics. 바카라 시스템 배팅 transfer torque refers to torque that acts on ferromagnets due to the injected 바카라 시스템 배팅-polarized currents. In this talk, I will review basic concept of the 바카라 시스템 배팅 transfer torque and also recent efforts to utilize this for device applications.
