摘要：

An energy-filtered magnetic induction mapping technique has been implemented on a JEOL 4000EX equipped with a Gatan imaging filter. A study of the magnetic domain structure in Terfenol-D, a magnetostrictive actuator material, is presented as an example application of the technique. The method is equivalent to differential phase contrast microscopy by the reciprocity theorem. Image simulations of all stages of the induction mapping process are shown to support these observations. (C) 1998 American Institue of Physics.
