Pure Fe powder was milled down to about 10 nm crystal size. In the as-milled sample, Mo Β¨ssbauer spectroscopy reveals the presence of two phases: crystallites and grain boundaries, the latter with a strongly disordered atomic configuration. The microstructural features affect the magnetisation behav

Using density functional theory DFT , the multiplicity of the ground state was determined for Fe S Cl 1y ions as well as the order of the excited spin states. A 6 6 6 method to determine the exchange integrals J of the Fe S 5q cluster is presented based on 6 6 these results and a spin-coupling alge
