摘要

Resonance frequency f_r of a LC circuit composed of a capacitor and a small solenoid, which contains Fe-based nanocrystalline powder cores, was measured. The properties of resonance frequency f_r shift dependence on external magnetic field, H_ex, have been investigated. The results showed that f_r evidently increases with H_ex and exhibits good linearity and sensitivity in the low field range. The large frequency shift is another form of giant magneto-impedance effect. The method can be used for measuring magnetic field or for improving the sensitivities of magnetic sensors.
