Abstract

A Mössbauer spectroscopic study of LiAlC2 doped with 57Fe (0.1 mol.%) has shown that the Fe in the material undergoes paramagnetic relaxation. The spectra recorded during the stages of the synthesis have shown a change in the paramagnetic relaxation rate which allows some conclusions to be drawn on the effect of molten fluxes.
