Abstract:
The influence of the magnetostriction materials demagnetization factor at room temperature on the magnetoimpedance effect of magnetoelectric composite oscillator is presented. Rectangular TDF and square TDF combine with the same piezoelectric PZT designed to form a magnetic composite oscillator,respectively. We compare the influence of demagnetization factor on magnetoimpedance,magnetocapacitance and magnetoinductance at resonance and anti-resonance frequencies. It was found that the variation of impedance,capacitance and inductance are basically similar with a dc magnetic field at resonance frequency. However,when the magnetostriction plate is rectangular,the impedance,capacitance and inductance of the magnetoelectric composite vibrator reaching to saturation required less magnetic fields than that of magnetostriction plate which is square. In the anti-resonance frequency,the influence of the demagnetization factor on the impedance and inductance varying with the magnetic field is basically same as that of resonance frequency except for capacitance. When the magnetostriction plate is square,the magnetoelectric composite oscillator capacitance fluctuates with the magnetic field intensity between 1 600 Oe and 1 700 Oe at anti-resonance frequency,and the magnetocapacitance is up to 44 000%. Considering magnetism,the effect of demagnetization factor on magnetoimpedance is analyzed theoretically. The study provides experimental and theoretical basis for magnetic field sensors in low magnetic detection.
