Discovered in the early 2000s, giant magnetostriction prompted many experimental and theoretical studies. However, the physical mechanism underlying this important functional property has not been fully understood, despite 20'years of continuous effort. The models currently under discussion are based on the concept of specifically ordered microscopic regions that emerge in a disordered crystal matrix. Of special importance in detecting suchlike structural states are techniques that involve the scattering of X-ray (synchrotron), electron, and neutron radiation. The current state of structural studies of Fe—Ga and Fe—Al alloys is reviewed, with the focus on neutron diffraction.

Keywords: Fe—Ga and Fe—Al alloys, giant magnetostriction, atomic structure, phase transitions, neutron diffraction
