摘要：

A simple, rugged Terfenol based magnetostrictive magnetometer prototype has been developed. Experiments were performed to determine the optimum operating point for the transducer and to study the characteristic of the diode laser sensor. A laboratory prototype has been constructed and evaluated under different field strengths and frequencies. Nonlinear responses were observed and their origin examined. The device has an ultimate sensitivity of 160 x 10(-6) A/m(= 2 micro+Oe).
