Changes induced by Pressure in the nuclear and magnetic structure of FeWO4
The wolframite-type MWO4 compounds, including FeWO4, exhibit intriguing properties such as magnetism and multiferroicity. FeWO4, characterized by a monoclinic crystal structure at room temperature (P2/c), displays antiferromagnetic behaviour with a Neżel temperature (TN) of 75 K under ambient pressure, attributed to superexchange interactions between Fe ions. Despite the known anisotropic compressibility of wolframites, the influence of pressure on the magnetism behaviour remains unexplored. FeWO4, present a commensurate propagation vector, (k=1/2 0 0), at ambient pressure. Ferromagnetic interactions among iron ions can be induced by pressure, according by DFT calculations, therefore this system is an ideal candidate for study the effects of high pressure. We request 2 days of beam time on XtremD operated at 10 GPa and 30 K to investigate the pressure-induced structural modifications leading to changes in the magnetic structure of FeWO4.
