Practical session: Magnetic structure determination and refinement

Sequential refinements
======================
Magnetic structure refinement with the Rietveld method of large amount of diffraction patterns. Sequential refinements.

The method has, in general, the following steps:

- Prepare a buffer file to be visualised with the help of WinPLOTR-2006
- Identify the critical temperatures and the name of the files corresponding
  to the starting of changes in the diffraction pattern
- Prepare PCR files appropriate for each homogeneous temperature intervals
  (by that we mean same number of crystalline phases)
- Refine selected patterns at different temperatures
- Run sequential refinements directly from WinPLOTR or preparing scripts
- Visualise the SEQ files using WinPLOTR
- Export selected parameters for further plotting with external software
  (KaleidaGraph, Origin, Excel, ...)
