  • Patent number: 12293781
    Abstract: The three-state spintronic device includes: a bottom electrode, a magnetic tunnel junction and a top electrode from bottom to top. The magnetic tunnel junction includes: a spin-orbit coupling layer, a ferromagnetic free layer, a barrier tunneling layer, a ferromagnetic reference layer, three local magnetic domain wall pinning centers and domain wall nucleation centers. An antisymmetric exchange interaction is modulated, and the magnetic domain wall pinning centers are embedded in an interface between a heavy metal and the ferromagnetic free layer. The magnetic domain wall nucleation centers are at two ends of the ferromagnetic free layer. A current pulse flows through the spin-orbit coupling layer to generate a spin current and the spin current is injected into the ferromagnetic free layer. Under a control of all-electrical controlled, an effective field of a spin-orbit torque drives domain wall to move and displace.

    Abstract: The present application relates to a power-off protection method and apparatus, a device, and a storage medium. The main technical solution includes: in response to power sourcing equipment (PSE) being about to stop supplying power to a power device (PD) within a predetermined time, sending a first link layer discovery protocol (LLDP) message to the PD; receiving a second LLDP message, which is replied by the PD according to the first LLDP message; and powering off the PD according to the second LLDP message. The present application can not only avoid the interruption of the current tasks of a PD as much as possible, but can also record power-off reasons, so as to facilitate tracing to maintain the normal operation of a device, thereby ensuring the security of data and the device.
