    Ca2Fe2O5 shows a first-order phase transition from space group Pnma to a modulated structure described in superspace group Imma(00g)s00. „In situ“ high-temperature single-crystal X-ray diffraction experiments revealed a phase coexistence over a range of ca. 25 K. In-situ high temperature transmission electron microscopy was utilized to prove it by an independent method.

    Ca2Fe2O5 vykazuje fázový přechod prvního druhu z prostorové group Pnma do modulované struktury popsané superprostorovou grupou Imma(00g)s00. Studium metodou "in-situ" difrakce na monokrystalu odhalila koexistenci obou fází v intervalu cca. 25 K. Pomocí metody "in-situ" transmisní elektronové mikroskopie se podařilo tento fakt potvrdit.
