Magnetic Structure Determination

This book presents the theoretical concepts needed to understand how to determine and classify a magnetic structure.  It is written for a non-expert audience, providing an accessible introduction to the topic in a concise manner, with all the essential concepts that beginners need to know. These concepts are illustrated with several examples providing a practical, hands-on approach to the subject. The following topics are covered:• Symmetry in physics and group theory concepts• Point and space groups• Scattering theory concepts: nuclear case (neutrons and X-ray)• Elastic coherent scattering; single crystal and powders• Magnetism concepts; description of magnetic structures (Fourier coefficients etc…)• Irreducible representations of a group• Landau theory of phase transitions• Neutron Magnetic Scattering• Solving and Classifying a magnetic structure• Magnetic space groups and magnetic super-space groups.• Typical experiments and software
