Dynamic Magneto-mechanical Behavior of an Iron-nickel-based Ferromagnetic Alloy with Constant Elasticity

다국어 초록 (Multilingual Abstract)

The dynamic magneto-mechanical behaviors in a type of iron-nickel-based ferromagnetic alloy with constant elasticity were investigated as a function of both the DC bias magnetic field (Hdc) and the frequency. The rectangular plate-like samples were excited to vibrate at a half-wavelength, longitudinal resonance by an AC magnetic field superimposed with various Hdc. The experimental results found that the strain coefficient at resonance reached 819.34 ㎚/A and the effective mechanical quality factor (Qm) was greater than 2000. The ratio of the maximum variation of the Young’s modulus over Hdc to the value of the Young’s modulus at a zero bias field was only ~0.83‰ because of the so-called constant elasticity. The resonant strain coefficients and Qm are strongly dependent on Hdc, which indicates a promising potential for use in DC and quasistatic magnetic field sensing.
