摘要	Magnetization versus dynamic stress of Fe81.6Ga18.4 is measured at 4.0 kA/m bias magnetic field and -7.0MPa compressive pre-stress. The magnetization and stress curves show that magnetization decreases with increasing compressive stress. Magnetization increases with increasing stress frequency at -20 MPa compounded stress. The output voltage from the pickup coil of a Galfenol force sensor is measured when the frequency and amplitude of dynamic force vary. The measurements show that the output voltage increases proportionally with increasing force frequency and amplitude. When the bias magnetic field is 4.0 kA/m, a maximum output voltage of 57mV is measured at -7.0MPa compressive pre-stress. (C) 2013 American Institute of Physics.
