摘要
To provide a method capable of easily and speedily measuring magnetic field strength dependence of properties of a magnetostrictive material.SOLUTION: A method for measuring properties of a magnetostrictive material comprises: a first excitation step S11 of generating a first magnetic field having a predetermined intensity; an impedance measurement step S13 of measuring the impedance of a coil that is installed in the first magnetic field and into which the magnetostrictive material is inserted; and a calculation step S14 of calculating the properties of the magnetostrictive material from the measurement result of the impedance, where the first excitation step S11, the impedance measurement step S13, and the calculation step S14 are repeated while changing the predetermined intensity.SELECTED DRAWING: Figure 2
