Hexagonal Frank--Kasper phases interpreted as modulated crystals.
The structures of the hexagonal Frank--Kasper phases F and K, which have been described in terms of the aggregation of clusters, are interpreted as modulated crystal structures. They are basically composed of two close-packed layers with ordered atomic vacancies rotated by 90 degrees to each other about their normal.
