Abstract:
The crystal structure of 0.06% Ce-doped SrMgF4, strontium magnesium tetrafluoride, reported by Ishizawa et al. [(2001), Acta Cryst. C57, 784-786] is shown to satisfy the structural criteria for ferroelectricity and to have a predicted Curie temperature T(c) approximately l450 K. The estimated spontaneous polarization P(s) approximately 11 x 10(-2) C x m(-2) is consistent with classification as a two-dimensional ferroelectric in which minor Delta(x) and major Delta(y), Delta(z) atomic coordinate component displacements are required for ferroelectric switching.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
