100 years after Max von Laue – Phase transitions and parametric symmetry modes: innovative methods in crystallography
Research report (imported) 2012 - Max Planck Institute for Solid State Research
Since the first diffraction patterns by Max von Laue 100 years ago, crystallography underwent an enormous development. Today's position sensitive detectors and radiation intensive synchrotron and neutron sources allow to measure powder diffractograms with high time resolution. This possibility and innovative analysis methods such as the coupling of symmetry modes with parametric Rietveld refinement allow for direct observation and investigation of phase transitions in solids.
