Abstract
Problem formulating. At present, there are noticeable difficulties in the development of compact and frequency-tunable generators and detectors of THz radiation operating at room temperatures. Antiferromagnets (AFM) are promising materials for creating such generators and detectors.
Goal. Carry out a theoretical study of THz electromagnetic wave detectors based on an antiferromagnet – heavy metal (HM) heterostructure.
Result. Two models of THz electromagnetic wave detectors based on the AFM-HM heterostructure are proposed. It is shown that the frequency dependence of the constant voltage of the detector has a resonant character with a peak corresponding to the antiferromagnetic resonance frequency.
Practical meaning. AFM-HM heterostructures can become the basis for quadratic resonant detectors of THz radiation.
