Doping Effects on Electronic Phase Separation in CaFe3O5

Abstract: Our recent study of CaFe3O5 revealed a remarkable discovery of electronic phase separation, similar to examples widely reported in manganite perovskites. Electronic phase separation is known to be very sensitive to perturbations so we areinvestigating effects of substituting Fe2+ by Co2+ or Mn2+. We have succeeded in preparing CaFe3-xMxO5 (M = Co, Mn) up to x = 0.5. High resolution PND is needed to observe phase separation and magnetic peaks in x = 0.01, 0.05, 0.10, 0.25 and 0.50 samples at 10-500 K. These will initially be screened at to check whether phase segregation has occurred. More time will be devoted to phase separated samples, with unsegregrated samples collected at just a few temperatures to measure magnetostrictive changes. The results will provide key insights into the electronic phase separation of CaFe3O5.
