This is a specialized workshop explaining the Magnetic option in Jana2006 for refinement of magnetic structures from neutron powder or single crystal data. Jana2006 includes tools for determination of magnetic symmetry from the symmetry of diffraction pattern as well as tools for representative analysis. It can find direct relationship between magnetic space or superspace group and corresponding representation and use it in the refinement. The underlying theory has been published in Acta Cryst.(2010),A66,449-655 and J. Phys. Condens. Matter (2012),24,163201(20pp)

Related topic is combination of data in Jana2006 because a magnetic structure based on powder neutron data can be refined together with nuclear structure based on more precice x-ray data. Another related topic concerns commensurate refinement becase magnetic q-vector is usually commensurate.

The workshop will cover following topics:

• Introduction to Jana2006
• Introduction to magnetic structures
• Introduction to magnetic symmetry
• Introduction to refinement of powder data with Jana2006
• Introduction to commensurate refinement with Jana2006
• Combination of data in Jana2006
• Solution of simple magnetic structures
• Solution of commensurate magnetic structures

Lecturers for this workshop: Vaclav Petricek, Juan Manuel Perez-Mato (Bilbao), Branton J. Campbell (Brigham), Ondrej Sipr (Prague) and Michal Dusek.

Each participant should bring a laptop with operating system Windows2000/XP/Vista/Windows7, with Administration rights. Installation of all necessary software will be done at the beginning of the workshop. Wireless internet connection including Eduroam is available at the lecture room. Limited number of computers can be provided to people without laptop (please inform us before the workshop that this would be needed)

Workshop cookbook cumulates examples from all Jana workshops. The latest version together with example files and installations files is available in jana page: cookbook.zip (~ 50MB). THE LINK IS UPDATED AFTER THE WORKSHOP, NOT BEFORE!
