Structural and magnetic properties of Ce 1 − x Sm x Fe 11 − y Ti 1 V y
Source abstract
Abstract
In order to find a promising trade-off permanent magnet material regarding a performance/cost-ratio, the Ce 1 − x Sm x Fe 11 − y Ti 1 V y -phase (x = 0–1; y = 0, 1) is analyzed in detail. In the first part, its existence range is studied (1000 °C) and the intrinsic magnetic properties are comprehensively determined. Diffraction experiments localize both structure-stabilizing transition metals on 8i-sites, explaining the measured reduction in saturation polarization as V is added. Curie temperatures increase upon Sm-substitution with a negligible dependence on V. Annealings of nanocrystalline material produced via intensive milling and melt-spinning show that V especially raises the obtainable maximum coercivities for Sm-rich phases (924 kA/m). In the second part, the promising magnetic properties of the nanocrystalline material are successfully transferred to the bulk state via hot-pressing. The isotropic Ce 0 . 5 Sm 0 . 5 Fe 10 Ti 1 V 1 -magnet (coercivity = 425 kA/m) is characterized by various means. Magnetic measurements, structural investigations and calculations of the elastic constants consider necessary factors for a successful texturing by die-upsetting (as accepted for Nd - Fe -B). The results are fundamental for further considerations in this active field of research.
