From volcanic ashes to magnetic zeolites: unravelling the iron oxide phase transitions by magnetic and advanced structural characterization
Volcanic ashes from Mount Etna are hydrothermally transformed into magnetic zeolites. Combined XAS and magnetometry reveal Fe phase transitions from olivine to magnetite-like and hematite phases, tuning oxidation states and magnetic responses.
