Rare earth permanent magnets constitute a mature technology, but the shock of the 2011
rare earth crisis led to the re-evaluation of many ideas from the 1980s and 1990s about …

A comprehensive review is presented of the extractive metallurgy of rare earths. The topics
covered are: world rare earth resources and production; ore processing and separation of …

This report presents the conceptual design of a new European research infrastructure
EuPRAXIA. The concept has been established over the last four years in a unique …

Magnetic materials research has entered a new and exciting period with the advent of the
ternary rare-earth-iron-boron compounds, R 2 Fe 14 B. From the fundamental physics …

Exchange hardening of nanostructured two-phase systems composed of an aligned hard
phase and a soft phase with high magnetization is investigated using an approach which …

Material choices for permanent magnets are analyzed in terms of energy product, anisotropy
and hardness parameter. Energy product is the main consideration for permanent magnets …

Magnetic nanostructures, such as dots and dot arrays, nanowires, multilayers and
nanojunctions, are reviewed and compared with bulk magnets. The emphasis is on the …

We discuss the mechanism of the coercivity enhancement by the grain boundary diffusion
process (GBDP) using Dy vapor based on detailed microstructural characterizations …

We have characterized the microstructures of as-sintered and optimally post-sinter annealed
Nd-rich Ga-doped Nd–Fe–B magnets by scanning electron microscopy (SEM) and …

Improving the coercivity of high La/Ce content multi-main-phase (MMP) sintered magnets is
crucial for promoting the use of La/Ce elements in permanent magnets. In this work, we used …
