Journal ArticleDOI
Stress, strain and technical magnetic properties in `exchange-spring' Nd2Fe14B + α-Fe nanocomposite magnets
TL;DR: In this paper, a modified Williamson-Hall analysis was applied to synchrotron transmission x-ray diffraction data obtained for a series of three melt-spun magnetic nanocomposite ''exchange-spring'' materials comprised of Nd2Fe14B and varying amounts of α-Fe ranging from 0-32 vol%.
Journal ArticleDOI
Low-moment ferrimagnetic phase of the Heusler compound Cr2CoAl
TL;DR: In this paper, stoichiometric Cr 2 CoAl samples were arc-melted and annealed at varying temperatures, followed by studies of their structural and magnetic properties, and high-resolution synchrotron X-ray diffraction revealed a chemically ordered Heusler phase in addition to CoAl and Cr phases.
Journal ArticleDOI
Modeling of permanent magnets: Interpretation of parameters obtained from the Jiles–Atherton hysteresis model
TL;DR: In this article, the Jiles-Atherton theory is used to calculate model parameters for permanent magnetization. But the results show that two of the calculated parameters, the saturation magnetization MS and the effective coercivity k, agree well with their directly determined analogs.
Journal ArticleDOI
Magnetization Processes in melt-spun Sm-Co-based alloys with the TbCu/sub 7/-type structure
TL;DR: In this paper, the initial magnetization processes in melt-spun Sm-Co alloys with remanent ratios above 0.7 have been studied, showing that nucleation-controlled processes dominate the magnetization process.
Journal ArticleDOI
Microstructure and magnetic properties of inert gas atomized rare earth permanent magnetic materials
TL;DR: In this article, the microstructure and magnetic properties of permanent magnet alloys based on the ternary Nd2Fe14B (2-14-1) composition have been studied as a function of particle size, both before and after heat treatment.
