Résumé
On a étudié par spectrométrie Mössbauer des composés interfolliaires de graphite G-FeCl3-x (0 ≤ x ≤ 1). L'emploi de feuille de Grafoil entraîne un effet de surface beaucoup plus important que celui attendu d'un graphite massif; il apparaît en plus des états Fe2+, dont la concentration augmente la température de Néel de G-FeCl3.
Abstract
A Mössbauer study on intercalation compounds of graphite with iron chloride, G-FeCl3-x (0 ≤ x ≤ 1) was reported. The use of Grafoil sheets as host graphite led to a surface effect to be more important than the use of bulk graphite, i.e. the appearence of an additional Fe2+ form. It was found that the Néel temperature regarded as for G-FeCl3 became higher with increase of Fe2+ concentration.
