- Abstract
X‐ray emission under electron‐channelling conditions is used to distinguish between a non‐centrosymmetric half‐Heusler and a centrosymmetric full‐Heusler crystal. For TiCo1.5+xSn the space‐group determination based on a Rietveld refinement procedure became challenging for increasing Co content (x > 0.2), while electron channelling proved successful for higher Co content (x = 0.35). This technique can be used on crystals as small as (10 nm)3.
