An in situ study of structural and magnetic order in LaSrCoFeO6-x
LaSrCoFeO6 is a rhombohedral perovskite, and can be reduced to the orthorhombic brownmillerite LaSrCoFeO5 in reducing atmospheres at around 600 deg C. This material is air... -
Investigation of the Negative Thermal Expansion in (Sr,Ca)FeO2 with FeO4 squa...
SrFeO2 bears a square planar oxygen coordination around Fe2+. The rarity of this structure led us to study the substitution of strontium by calcium and we obtained the solid...
