Magnetic hardening studies in sintered Sm„Co,Cux ,Fe,Zr...z 2:17 high temperature magnets

Lorentz microscopy combined with conventional transmission electron microscopy were used to image the magnetic domains and microstructures of sintered Sm~CobalCuxFe0.06Zr0.03)z ~0.088<x <0.128; 5.8<z<7.2! permanent magnets which were specifically designed for high temperature applications. The microstructural data were correlated with the magnetic measurements to understand the origin of coerci...

Anisotropic bonded magnets fabricated via surfactant-assisted ball milling and magnetic-field processing

Anisotropic bonded magnets are fabricated by surfactant-assisted ball milling in a magnetic field and magnetic field alignment of the milled chip-like nanoparticles of the Sm–Co and Nd–Fe–B materials. It is found that the application of magnetic fields during the ball milling strengthens the anisotropy of the chips and therefore improves the alignment. For SmCo5 phase-based chips, for instance,...
