Abstract

We propose a modified coherent rotation model to describe recently observed phenomena in the magnetostrictive responses of Metglas transducers used in fiber-optic magnetometers. A technique to extract the values of the transducer parameters is described. Predictions of the performance of a cylindrical transducer based on the measured values for the transducer parameters are presented and compared to the experimental result.
