15 صفحه اولMagnetic symmetry and determination of magnetic structures
In this seminar we take a look at symmetry operations in three dimensions (3D) and show how magnetic symmetries are derived from them. Then we present the basics of group theory and demonstrate the strength of representation analysis in narrowing down the spectrum of possible magnetic structures in a magnetic material. In the end we apply these methods to the example of CuSe2O5: we briefly pres...

15 صفحه اولMagnetic Structure Analysis and Group Theory
R6sum6. L'analyse de structures magnktiques par la thkorie des groupes (analyse de reprksentations) est baste sur la transformation de vecteurs spins, situks dans une position cristallographique donnee, sous les opkrations de symktrie d'un groupe d'espace G ou sous-groupe Gk du cristal dans lequel se trouve la structure magnktique. Le vecteur d'onde k caracterisant le groupe de translation est ...
متن کاملTheory of commensurable magnetic structures in holmium.
The tendency for the period of the helically ordered moments in holmium to lock into values which are commensurable with the lattice is studied theoretically as a function of temperature and magnetic field. The commensurable effects are derived in the mean-field approximation from numerical calculations of the free energy of various commensurable structures, and the results are compared with th...
