Title (EN) VECTOR MAGNETIC FIELD SENSORS USING SPIN-ORBIT READOUT
(FR) CAPTEURS DE CHAMP MAGNÉTIQUE VECTORIEL UTILISANT UNE LECTURE DE SPIN-ORBITE
Abstract:
(EN) A magnetic field sensor is provided which comprises: a magnetic field sensor comprising: a magnet (e.g., a ferromagnet or paramagnet); a first layer comprising an inverse spin orbit coupling material, wherein the first layer is adjacent to the magnet; and a second layer comprising a first non-magnetic metal, wherein the second layer is adjacent to the first layer. A system is provided which comprises: a processor; a memory coupled to the processor, the memory comprising: a heat spreading layer; a transition metal layer adjacent to the heat spreading layer; and a magnetic recording layer adjacent to the transition metal layer, wherein a magnetic field sensor comprising an inverse spin orbit coupling material is to be positioned near enough to the magnetic recording layer to sense magnetic field from the magnetic recording layer; and a wireless interface to allow the processor to communicate with another device.
(FR) L'invention concerne un capteur de champ magnétique qui comprend : un capteur de champ magnétique comprenant : un aimant (par exemple, un aimant ferromagnétique ou un aimant paramagnétique) ; une première couche comprenant un matériau de couplage Russell-Saunders inverse, la première couche étant adjacente à l'aimant ; et une seconde couche comprenant un premier métal non magnétique, la seconde couche étant adjacente à la première couche. L'invention concerne également un système comprenant : un processeur ; une mémoire couplée au processeur, la mémoire comprenant : une couche de diffusion de chaleur ; une couche de métal de transition adjacente à la couche de diffusion de chaleur ; et une couche d'enregistrement magnétique adjacente à la couche de métal de transition, un capteur de champ magnétique comprenant un matériau de couplage Russell-Saunders inverse devant être positionné suffisamment près de la couche d'enregistrement magnétique pour détecter un champ magnétique à partir de la couche d'enregistrement magnétique ; et une interface sans fil permettant au processeur de communiquer avec un autre dispositif.
