Figure 1
Schematic presentation of the disordering in the 8h positions with respect to the chemical compositions for (a) disordered Mn14.9Co15.5Ge6.6, (b) partially disordered Mn14Co16.2Ge6.8 and (c) hypothetically ordered `Mn14Co18Ge5'. All projections of the orthorhombic unit cells are presented on the ba plane. Atoms names are as used in Table 2. |
