Spectroscopic characterization of Fe-doped synthetic

By EPR, DRS spectroscopic analyses and magnetic investigations, Mg and/or Si ion replacement by Fe 3 in a synthetic geomimetic chrysotile structure has been investigated. The results highlight that, as a function of the Fe doping extent and of the Fe doping process, iron can replace both Mg and Si sites.
