ملخص

Some of the electrical properties of chromium-substituted spinel Li _0.5Cr_xFe_2.25-xO₄ with 0.15≤ x ≤1.85, synthesized at 1200 °C for 12 h, are examined through impedance measurements and analysis. The electrical resistivity, relaxation frequencies and dielectric constant of Li_0.5Cr_xFe _2.25-xO₄ have been investigated versus the composition x. The behavior of these can be satisfactorily described by a hopping mechanism of charge carriers between Fe²⁺ and Fe³⁺ ions on octahedral sites of the spinel lattice.
