Electrical spectrum of Co[Cr.sub.2][S.sub.3.5][Se.sub.0.5]

Electrical spectrum of Co[Cr.sub.2][S.sub.3.5][Se.sub.0.5]

It has been shown that, at temperatures of 140-300 K in the frequency range from 0.065 to 6 Hz, the permittivities [epsilon]' and [epsilon]" of Co[Cr.sub.2][S.sub.3.5][Se.sub.0.5] increase with an increase in the temperature according to the law [[epsilon].sub.i] = [a.sup.i.sub.1] + [a.sup...

Zusammenfassung:It has been shown that, at temperatures of 140-300 K in the frequency range from 0.065 to 6 Hz, the permittivities [epsilon]' and [epsilon]" of Co[Cr.sub.2][S.sub.3.5][Se.sub.0.5] increase with an increase in the temperature according to the law [[epsilon].sub.i] = [a.sup.i.sub.1] + [a.sup.j.sub.2] exp(-[DELTA][x.sub.i] /kT). As the frequency increases, the permittivity decreases. An analysis has demonstrated that the main polarization mechanism is the orientation polarization.
