Abstract
A temperature-dependent, single crystal x-ray diffraction study of the giant magnetocaloric material, , across its Curie temperature (276 K) reveals that the simultaneous orthorhombic to monoclinic transition occurs by a shear mechanism in which the dimers that are richer in Ge increase their distances by 0.859(3) Å and lead to twinning. The structural transition changes the electronic structure, and provides an atomic-level model for the change in magnetic behavior with temperature in the .
