  • Single magnetic-layer microwave oscillator
    Patent number: 11533020
    Abstract: A method and system for generating voltage and/or current oscillations in a single magnetic layer is provided. The method comprises applying a direct voltage/current to the layer in a longitudinal direction; and developing a longitudinal voltage between a pair of longitudinal voltage leads and/or a transverse voltage between a pair of transverse voltage leads. The magnetic layer comprises a ferrimagnetic or antiferrimagnetic material having a first and second magnetic sub-lattice, wherein the first sub-lattice is a dominant sub-lattice such that the charge carriers at the Fermi energy originate predominantly from the dominant sub-lattice and the charge carriers at the Fermi energy are spin polarised. In some embodiments, the dominant current carrying sub-lattice may lack inversion symmetry.
