WebMar 17, 2024 · Commensurate means that the ration of two parameters is an integer or, more generally, a ratio of integers. For example, if we consider a one-dimensional lattice … There are basically three types of superstructures in crystals: When a crystalline material that contains atoms with uncompensated electron spins is cooled down, ordering of these spins generally occurs once the thermal energy is small enough not to overrule the interactions between neighboring spins. If the ordering does not exhibit the same symmetry as the original unit cell of the crystallographic lattice, a superstructure will result. In thi…
