概要
- 論文の詳細を見る
Fourier transforms of the dipole-dipole interaction D(q) are computed inorthorhombic simple, body-centered and face-centered lattices. The ratios ofthe lattice constants a and b to the lattice constant c are varied as parameters.The modulation wave vectors q-?. where D(q) takes the minimum value areshown in a/c-b/c planes. Sinusoidal arrays are found to be of the minimum energyin wide regions in these planes in the cases of body-centered and face-centeredlattices. Contributions to D(q) from sublattices are separately calculated. Thedifferent arc and b/c dependences of them are found to result in the deviation ofq.... from the origin (the ferroelectric array) or zone boundaries (antiferroelectricarrays) in the (-space.
