| Abstract | dc.description.abstract | The solid solutions Cu2Fe1-XCoXSnS 4, with stannite-type structure are stable up to about 800C. The electrical properties of the Cu2Fe1-XCo XSnS4 ceramic were investigated by complex impedance. The real and imaginary dielectric permittivity dependence with the temperature were measured between 10kHz and 1 MHz in temperature range 77-280K, finding that the ceramic present the characteristics behavior of a dielectric relaxation between 100 and 250 K, with a maximum at approximately 200 K. The electric permittivity found has orders of magnitude between 102 and 103. A space charge polarization mechanism is suggested to explain the observed electric relaxation. | |
