Internal magnetostriction observed by X-ray diffraction in iron

A new technique to observe the internal mode of the magnetostriction with sufficient sensitivity using X-ray diffraction was developed. As a result, the antisymmetry part of the diffraction intensity change was proportional to a flipping ratio of an X-ray magnetic diffraction (XMD). This technique using X-rays has the potential to simultaneously investigate magnetostriction together with XMD at local coextensive specimen volumes.
