Rare earth permanent magnets are essential in a plethora of electrical machine and
renewable energy. Nd-Fe-B magnets account for half of the market share of permanent …

This book presents an overview of recent and emerging additive manufacturing (AM)
techniques and their applications. It explains several of the processes developed using …

In the present work, we explore the influence of a surface-bulk coercivity gradient in Nd-Fe-B
magnets produced by the Grain Boundary Diffusion Process (GBDP) on the overall …

The rare-earth crisis, which peaked in the summer of 2011 with the prices of both light and
heavy rare earths soaring to unprecedented levels, brought about the widespread …

The understanding of a coercivity mechanism in high performance Nd–Fe–B permanent
magnets relies on the analysis of magnetic properties of all phases present in magnets. By …

Magnetic features of transition metal (TM)-Rare earth (RE) heterostructures were studied
using atomistic simulations. The ferromagnetic ordering temperature of pure Cobalt (Co) and …

We present a self-consistent local mean-field analysis of core-shell nanoparticles with
ferromagnetic materials but with antiferromagnetic interface exchange coupling. The …

AlNiCo-8 alloys were synthesized by annealing a mixture of Al/Ni/Co/Cu/Fe/Ti oxides and
CaH 2 in an inert gas environment. In four parallel experiments, the annealing temperature …

Os ímãs de terras-raras mostraram-se importantes no desenvolvimento de dispositivos
eletromagnéticos. Embora estes ímãs tenham promovido avanços, a baixa temperatura de …
