WebThe first Brillouin zone of an fcc lattice has the same shape (a truncated octahedron) as the Wigner-Seitz cell of a bcc lattice. Some crystals with an fcc Bravais lattice are Al, Cu, C (diamond), Si, Ge, Ni, Ag, Pt, Au, Pb, NaCl. Cut-out pattern to make a paper model of the fcc Brillouin zone. Punkte hoher Symmetrie des fcc-Gitters. WebA sharp enhancement is observed when θ is near the crystallographic high-symmetry directions <100>. This can be contrasted with the behavior at T = 6.5 K, which shows a smoothly varying profile captured by conventional AMR and has the symmetry of the underlying nonmagnetic group symmetry ( 29 ).
