✦ Synopsis

Synthesis and X-Ray Diffraction Studies of Dysprosium-Calcium Ferrites Dy1-xCaxFeO3-y (0 ≤ x ≤ 2/3).

-The title compounds are prepared by solid state reaction of the binary oxides at 1200 • C in air (72 h). The obtained samples are single phase, orthorhombic compounds belonging to space group Pbnm ( powder XRD). The substitution of divalent Ca for trivalent Dy leads to a decrease of the unit cell dimensions up to x = 0.1; further substitution does not affect the unit cell volume. -(LI,
