Description
Summary:The EPR method is used to investigate the synthesized basic [CuGaTe.sub.2] compound and [CuGaTe.sub.2]{Mn} compounds doped with Mn The [CuGaTe.sub.2] EPR spectra obtained testify to the formation of the Jahn--Teller copper centers with g-tensors having axial symmetry that differ by values of the main g-tensor components ([g.sub.[parallel]] and [g.sub.[perpendicular to]]). The intensive line with [g.sub.eff3] = 1.996 [+ or -] 0.001 registered for samples of [CuGaTe.sub.2]{Mn} compounds is associated with the presence of centers formed by manganese. Keywords: spintronics, electron paramagnetic resonance, chalcopyrite semiconductors, doping.
