  1. 1. Modulations in B8-type Intermetallics

    Författare :Margareta Elding-Pontén; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron diffraction; X-ray diffraction; Superspace group; Edshammar polyhedron; Mn-Sn; Cu-In; B8-type; Ni2In; NiAs; Modulation; Superstructure; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : The B8-type regions of the Mn-Sn and Cu-In systems have been investigated by means of electron and X-ray diffraction. The importance of the combination of these techniques in the study of B8-type phases is pointed out. In addition to the B8-type phases an alloy with a quasicrystal approximant structure has been studied. LÄS MER
