Abstract

Single-crystal X-ray diffraction coupled with TEM and SAD investigations demonstrate that Gd5Si1.5Ge2.5 exists as two distinct structural phases at room temperature:  the orthorhombic Sm5Ge4-type and the monoclinic Gd5Si2Ge2-type. This phenomenon occurs from the “nanoscale zippers” involving (Si, Ge) dimers that form or break bonds between the fundamental building units.
