摘要：
In this study, the feasibility of using magnetostrictive sensors for measuring magnetic fields was explored. The sensors were fabricated using optical fibers containing Bragg gratings attached to a magnetostrictive material in bulk or in the form of particulate composites. The responses under effects of uniform and gradient magnetic field were analyzed. They have shown a strong anisotropy regarding the shape of the magnetostrictive material when it is in bulk form in comparison to when it was made of the particulate composites.
