✦ Synopsis

We have implemented an energy-filtered magnetic induction mapping technique on a JEOL 4000EX equipped with a Gatan Imaging Filter. We present an example application of the technique to the study of the magnetic domain structure in Terfenol-D, a magnetostrictive actuator material. The method is equivalent to Differential Phase Contrast microscopy by the reciprocity theorem. To support the observations we have also implemented an image simulation algorithm which permits direct computation of all stages of the induction mapping process.
