title: Detection scheme in a fiber-optic magnetic-field sensor free from ambiguity due to material magnetic hysteresis.
abstract: A new technique has been demonstrated in the detection of low-frequency or dc magnetic fields in an optical-fiber interferometric sensor using the magnetostrictive approach. This technique permits magnetic-field measurements free of ambiguity associated with hysteresis effects of the material.
