SPIN CURRENT TO CHARGE CURRENT CONVERTER BASED ON A HETEROSTRUCTURE OF TRANSITION METAL PEROVSKITES Russian patent published in 2022 - IPC H01L29/82 H01L43/10 G11C11/16 

FIELD: quantum electronics.

SUBSTANCE: invention relates to spintronics devices and can be used in information systems and radio engineering devices of the microwave range. The spin current to charge current converter contains a heterostructure formed on a crystalline substrate based on thin films of transition metal perovskites, including a ferromagnetic layer of strontium doped manganite La_0.7Sr_0.3MpO₃ and a detecting layer of 5d oxide film SrIrO₃, and film metal electrodes connected to an electrical control circuit and voltage registration, while according to the invention the heterostructure has planar geometry, while the crystal substrate is made of neodymium gallate NdGaO₃, the crystallographic plane (110) of which coincides with the direction of the magnetization vector of the manganite layer La_0.7Sr_0.3MpO₃ formed on the substrate, and the detecting layer of the 5d oxide film SgIgO₃ is applied over the aforementioned manganite layer, with the film metal electrodes are placed in the same plane and located on the free surface of the detecting layer.

EFFECT: invention provides an increase in the sensitivity of the output signal while ensuring the manufacturability of the structure formation process.
