Synthesis, single-crystal X-ray diffraction and Mössbauer characterization of novel iron hydrides under high pressure

The aim of this proposal is to synthesize, study the crystal chemistry, high-pressure behaviour and electronic and magnetic states of Fe in iron hydrides in diamond anvil cells at conditions close to the Earth's core by means of single crystal XRD and SMS. An analysis of the data obtained can play an important role in obtaining new compounds of a strong d-d electron-correlated system with interesting physical properties, such as superconductivity or unusual magnetic ordering that could be of interest for potential technical applications. Moreover, the investigation of such structures can be the key to understanding the composition of the Earth’s core and Earth-like rocky planets and their dynamics.
