Abstract: A novel type of magnetometer is introduced.The zero magnetostrictive amorphous material ribbon is used as the probe's core,and multivibrator resonance oscillator in the circuit design is adopted.The magnetometer has good performances such as simple structure,convenience operation and high response frequency.The response frequency is up to 5 kHz.The operation principle of magnetometer is explained and its applications in measuring some facilities on satellite are studied. Subject Term Magnetometer Amorphous compound Multivibrator Research] , in which HCR, HVR and HPR is the ratio of current, voltage and power of the Holographic Ratio Network respectively. Based on this relation an ideal attenuator can be designed according to the following equation: A=20 Log(HCR)=20 Log(HVR)=10 Log(HPR). Experiments on models are full proof the theory of Holographic Ratio Network is valid. , in which HCR, HVR and HPR is the ratio of current, voltage and power of the Holographic Ratio Network respectively.
