Journal ArticleDOI
Electron microscopy of grain boundaries: An application to RE-Fe-B (RE = Pr or Nd) magnetic materials
TL;DR: In this paper, a method using small-angle dark-field imaging based on inner-potential differences at the grain boundaries, combined with high-resolution electron microscopy and nanoscale chemical analysis, was proposed to study the grain boundary of the technologically important permanent magnets.
Journal ArticleDOI
Engineering magnetic nanocomposite microstructures
TL;DR: In this article, manipulation of multiple alloying additions leads to the synthesis of magnetically optimum nanoscale metal matrix composite microstructures in a 9-element modified Nd-Fe-B alloy.
Journal ArticleDOI
The CoPt system: a natural exchange spring
TL;DR: In this article, a model for the study of interphase interactions in exchange-spring systems in thin-film form is proposed, and coupled magnetic and transmission electron microscopy studies reveal simple relationships between the volume percent of ordered L10 phase, coercivity and the magnetic exchange within the samples.
Journal ArticleDOI

TL;DR: In this paper, the coexistence of ferromagnetic and antiferromagnetic phases in a (3 at.%)Pd-doped FeRh epilayer was observed using X-ray photoelectron emission microscopy.
Journal ArticleDOI
The effect of Nb additions on the thermal stability of melt-spun Nd2Fe14B
TL;DR: In this article, a superconducting quantum interference device (SQUID) magnetometry was performed on two samples of melt-spun and optimally annealed Nd2Fe14B; one sample contained 2.3 wt% Nb and one was Nb-free.
