Magnetostructural and disorder-order transformations studied by in-situ synchrotron X-ray diffraction

The current proposal for the use of Synchrotron-Radiation Powder X-ray Diffraction (SR-PXD) aims at the investigation of the crystal structures and phase transformations in two main classes of materials for magnetic applications:
1) In equiatomic FeNi, an ordering of the system develops a hard magnetic phase that is a promising phase for future use as a rare earth-free permanent magnet;
2) RCo2-yXy where R is a lanthanide element and X is a transition metal, which undergoes a magnetostructural transition at around 100 K.
