OSCILLATOR FOR TERAHERTZ GENERATOR Russian patent published in 2021 - IPC H01L31/102 

FIELD: applied physics.

SUBSTANCE: invention relates to applied physics and can be used in measuring technology for generating and receiving radiation in the frequency range 0.1-5 THz. The oscillator for a terahertz generator comprises a heterostructure based on layers of antiferromagnetic dielectric and platinum formed on a substrate and a source for passing direct current through a platinum layer. The antiferromagnetic dielectric is selected from the group of substances having magnetoelastic properties, the heterostructure comprises a means for guiding and regulating magnetic anisotropy fields in an antiferromagnetic dielectric designed in the form of a piezoelectric element with two electrodes for connection to an independent voltage source. The first electrode is located on the outer surface of the piezoelectric element and the other electrode is said platinum layer, wherein the hard axis of magnetic anisotropy of the antiferromagnetic dielectric lies in the plane of the heterostructure.

EFFECT: invention aims at solving the problem of producing an oscillator for a terahertz generator, the parameters of which can be adjusted by means of two independent control values: electric current and elastic deformation by means of a piezoelectric element controlled by electrical potential.
