Abstract
Samples of Eu1-xCaxFeO3-y (x = 0.0, 0.2-1.0) were prepared by the soli d state reaction method. X-ray diffraction measurements showed that co mpounds for x < 0.6 have perovskite structure. Three magnetic and one doublet species were observed at room temperature in the Mossbauer spe ctra. The Fe ions are all in a trivalent state. The changes of isomer shift, quadrupole splitting and intensity with composition are discuss ed.
