title: Nonlinear impedance of 50Bi2VO5.5-50SrB4O7 glass measured with impedance spectroscopy method at low temperature region

description: The nonlinear electrcial properties of 50(Bi2VO5.5)-50SrB4O7 glass was measured by impedance spectroscopy method. 
In order to prepare glasses two compounds: Bi2VO5.5 and SrB4O7 were synthesized via a solid state reaction route. The Bi2VO5.5 was synthesized from the stoichiometric mixture of initial powders of Bi2O3 and V2O5 which were ball-milled in pure acetone for 6 h at room temperature. The milling was performed in steps of 1 h with rest intervals of 10min. The mixture was heated up to 1020K in air and kept at this temperature for 24 h. The heating and cooling rate was of 50K h-1. The obtained powder was checked by X-ray diffraction method. The SrB4O7 was synthesized from the stoichiometric mixture of analytical grade SrCO3 and H3BO3 which were mashed in a mortar. Next the mixture was heated up to 1073K and kept at this temperature for 12 h. Samples of a composition of 50Bi2VO5.5–50SrB4O7 (in mol%) were prepared by the conventional melt quenching technique. The melting was conducted in alumina crucibles at 1373K for 2 h. The melts were poured onto a preheated (573 K) brass plate and pressed by another plate to obtain flat circular disks of 1–2mm thickness and 20–30mm diameter. 
For the electrical measurements gold electrodes were evaporated at the preheated samples. Impedance measurements were carried out in the temperature range from 153 K to 423 K, with the ac voltage of 1 Vrms with Concept 40 broadband dielectric spectrometer. The higher harmonic components (harmonic 0, harmonic 1 and harmonic 2) were measured up to frequency of 1000 Hz. Here the impedance for harmonic components was defined as the ratio of the voltage base wave to the n-th harmonic current component: Zn∗= U0∗/In∗, where Zn⁎ including the base wave generally depend on the sample voltage U1⁎ base wave amplitude. From Zn⁎ allother independent variables are calculated. The dependence of current density on the cosinusoidal electric field E(t)= E0cos(ωt) leads to the following expression:
j´ = σ´0hE0 cos (ωt) + σ´1hE0 cos (2ωt) + σ´2hE0 cos (3ωt) + …Where σ´0h denotes base conductivity, while σ´1h, σ´2h etc. are higher harmonics conductivity. The admittivity for harmonic components with n ≥1, is calculated from relation σ⁎n = i2πfε0ε⁎n.
