Symmetry of Magnetically Ordered Three Dimensional Octagonal Quasicrystals
The theory of magnetic symmetry in quasicrystals, described in a companion paper [Acta Crystallographica AXX (2003) xxx-xxx], is used to enumerate all 3-dimensional octagonal spin point groups and spin space-group types, and calculate the resulting selection rules for neutron diffraction experiments. 1. Introduction We enumerate here all three-dimensional octagonal spin groups and calculate the...
متن کاملCrystallography and Magnetic Phenomena
This essay describes the development of groups used for the specification of symmetries from ordinary and magnetic point groups to Fedorov and magnetic space groups, as well as other varieties of groups useful in the study of symmetric objects. In particular, we consider the problem of some incorrectness in Vol. A of the International Tables for Crystallography. Some results of tensor calculus ...
متن کاملMagnetic space and superspace groups, representation analysis: competing or friendly concepts?
Although encoded in theoretical works, relationships between the diffraction symmetry of magnetic structures and magnetic space/superspace groups are often ignored in practical applications. It is shown that magnetic symmetry operations have a direct impact through the rotation parts in the diffraction symmetry of the crystal and can be used to simplify calculations of magnetic structure factor...
متن کاملMagnetically ordered quasicrystals: enumeration of spin groups and calculation of magnetic selection rules.
Details are given of the theory of magnetic symmetry in quasicrystals, which has previously only been outlined. A practical formalism is developed for the enumeration of spin point groups and spin space groups, and for the calculation of selection rules for neutron scattering experiments. The formalism is demonstrated using the simple, yet non-trivial, example of magnetically ordered octagonal ...
متن کاملEffects of Color and Glitter on the Removable Space Maintainer
Introduction: It may be necessary to make some modifications to the removable space maintainers for the persuasion of children to use this device. However, modification of the polymethyl methacrylate (PMMA) may affect its mechanical properties as well. Therefore, the present study aimed to evaluate the effects of color and glitter on the flexural strength of PMMA. Meth...
متن کاملSymmetry relations of magnetic twin laws.
Symmetry relationships between two simultaneously observed domain states (domain pair) are used to determine physical properties that can distinguish between the observed domains. Here the tabulation of these symmetry relationships is extended from non-magnetic cases to magnetic cases, in terms of magnetic point groups, i.e. all possible magnetic symmetry groups and magnetic twinning groups of ...
