dc.descriptionThe jarosite family of minerals contain antiferromagnetically coupled Fe3+ ions that make up the kagome network. This geometric arrangement of the Fe3+ ions causes magnetic frustration that results in exotic electronic ground states, e.g. spin glasses and spin liquids. Synthesic research into jarosites has focused on producing near perfect stoichiometry to eliminate possible magnetic disorder. An new oxidative synthesis method has been devel-oped for the potassium, sodium, rubidium and ammonium jarosites that leads to high Fe coverage. We show through the identification of a meta-stable intermediate, using powder X-ray diffraction, how near perfect Fe coverage arises using this method. Understanding this new mechanism for jarosite formation suggests that is it possible to synthesis hydronium jarosite, an unconventional spin glass, with a very high Fe coverage.
