Crystal structure and magnetic properties of cerium‐iron compounds

Abstract

Abstract The crystal structure, the magnetic properties, and the phase relations of cerium‐iron compounds have been investigated. A phase diagram is presented. Lattice constants are given for CeFe 2 , α‐Ce 2 Fe 17 , and β‐Ce 2 Fe 17 . The compound CeFe 2 is ferromagnetic with T c = 230° K. Investigations by means of the Mössbauer effect and bulk magnetization indicate an antiferromagnetic–ferromagnetic transition near 70° K and an antiferromagnetic‐paramagnetic transition close to 270° K for the compound β‐Ce 2 Fe 17 . The ordering temperatures and saturation moments for the CeFe compounds are compared with magnetic data presented for the isostructural YFe compounds.
