资源简介：
The linear and nonlinear impedance ofglasses doped with iron oxide were measured. Glass samples (50 SiO2-50-xPbO-xFe2O3 in mol%) were prepared by the conventional melt quenching technique. The substrates were powdered in a mortar and melted in Al2O3 crucibles. The melting was conducted in air at 1623K. The melts were poured out on plate heated up to 673K and formed into small circular-shaped pellets (about 1,5 mm thick and 20 mm in diameter). Next glasses were annealing at the 673K and cooling with furnance. After a polishing, golden electrodes were evaporated at both sides of preheated samples in vacuum, for the electrical conductivity measurements. The linear and nonlinear impedance spectra were measured in the frequency range of 1 mHz to 1 MHz and in the temperature range of 153K to 483K by Concept 40 broadband dielectric spectrometer.
