Ensembles of parallel nanowires (NWs) consist of the parts from different ferromagnetic metals (for example, FeNi/Co/FeNi)
that are obtained by the method of template synthesis. It was shown that such samples could be the sources of electromagnetic
emission–irradiation of the terahertz (THz) range. It could be detected when the current passed through the contacts at the sample
with these wires. The method of obtaining NWs was proposed (two-bath galvanic technique), and formation of contact layers at the
surface (parallel narrow strips of metal) was proposed. The features of these radiation were investigated—its threshold characteristic,
its nonthermal origin, and spatial distribution. The calculation was also presented, which demonstrated the possibility of detecting
of THz irradiation, using a ensemble of such NWs, included ferromagnetic metal and antiferromagnetic metal.
