MODULATIONS OF INTERMETALLIC B8-TYPE PHASES. Sven Lidin, Margareta Elding & Lars Stenberg. Inorganic chemistry, Arrhenius Laboratory, Stockholm University, 106 91 Stockholm

Intermetallic B8 type phases exhibit a full spectrum of modes of ordering from short period, commensurate, superstructures to long period or incommensurate modulations and short range order as indicated by highly structured diffuse scattering. We will present results on modulated structures from the systems Cu-Sn, Co-Sn, Cu-In, Ni-Bi and Mn-Sn derived by electron diffraction and high resolution electron microscopy, single crystal X-ray diffraction and X-ray powder diffraction.
