WebFrom Table 3 we notice that for the face centered cubic (f.c.c.) lattice there are two symmetry points and two possible propagation vectors for simple antiferromagnetic ordering with k = H /2: (0, 0, 1) and corresponding to the so-called type-I and type-II antiferromagnetic ordering, respectively. WebThe face-centred cubic (FCC) has a coordination number of 12. One-eighth of an atom at each of the eight corners i.e 8 × 1 / 8 = 1 atom from the corners. One-half of an atom on each of the six faces i.e 6 × 1 / 2 = 3 atoms from the faces. Hence, there is a total of 4 atoms in a face centred cubic unit cell. Suggest Corrections.
