名称及摘要

Magnetostrictive Film, Magnetostrictive Element, Torque Sensor, Force Sensor, Pressure Sensor, And Manufacturing Method Therefor
For providing a magnetostrictive film that can exhibit high magnetostrictive properties in the vicinity of zero magnetic field and their manufacturing methods, a magnetostrictive film thermal sprayed on an object under test includes a metallic glass film subjected to thermal processing at a temperature lower than the glass transition temperature and not lower than the Curie point, and shows a linearity between the magnetic field and the magnetostriction in at least a part of the magnetic field from −15 kA/m to +15 kA/m (both inclusive).
