Quasi-one-dimensional chains of magnetic tunnel junctions as a source of THz radiation

The mechanism of formation of spin nonequilibrium with inverse population in spin subbands in quasi-one- dimensional chains of magnetic metal tunnel junctions is considered. The ability of induced spin-injected radiation is discussed. A model of a one-dimensional chain of ferromagnetic metal grains separated by a tunneling dielectric under the influence of electric current is considered. The radiation spectra of grainy metamaterials were measured in the terahertz range depending on the average current density in the Q1D-labyrinth structures.
