Abstract: Provided are a spin logic device based on a magnetic tunnel junction and an electronic apparatus comprising the same. According to an embodiment, the spin logic device may comprise: a current wiring; a magnetic tunnel junction, which comprises a free magnetic layer, a fixed magnetic layer, and a potential barrier layer located therebetween, which are stacked on the current wiring; and a current source for providing an input current to the current wiring, wherein the input current comprises a first, a second, and a third in-plane currents, directions of which are different from a direction of a magnetization axis of the free magnetic layer or there is a vertical component in that direction, and the first and the second in-plane currents are logical input currents while the third in-plane current is used to control the implementation mode of the spin logic device.

Abstract: The present disclosure relates to a magnon spin valve device, a magnon sensor, a magnon field effect transistor, a magnon tunnel junction and a magnon memory. A magnon spin valve device may comprise a first ferromagnetic insulation layer, a non-magnetic conductive layer disposed on the first ferromagnetic insulation layer, and a second ferromagnetic insulation layer disposed on the non-magnetic conductive layer.

Abstract: An antigenic characterization method using polyclonal antibody-based proximity ligation assays (polyPLA). Methods, kits, and other tools disclosed herein are useful in detecting microbial antigenic variants in samples, including clinical samples. The methods and kits have great utility in detecting antigenic variants for pathogenic microbes, including viruses, bacteria, and parasites.
