Title: Pressure induced spin transition revealed by iron M{sub 2,3}-edge spectroscopy

Abstract

We present a method to characterize pressure induced magnetic high to low spin transition in iron sulphide using x-ray Raman scattering spectroscopy at the iron M{sub 2,3}-edge. The advantage of this method is that the observed spectral changes between pressures of 1.7 GPa and 10.1 GPa can be used with the help of atomic multiplet calculations to determine the crystal field splitting parameters associated with the spin transition. We discuss the potential of this M{sub 2,3}-edge spectroscopy to investigate the irons electronic spin state in-situ at the conditions of the inner Earth, i.e., at high temperature and high pressure, providing exciting opportunities for geophysical and materials science applications.
