Perspective and Prospects for Rare Earth Permanent Magnets

Engineering, 2020
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 possible new hard magnets containing little or no rare earth (or heavy rare ...

Heavy rare earth free, free rare earth and rare earth free magnets - Vision and reality

Scripta Materialia, 2018
It is commonly understood that among the intermetallic phases used for permanent magnets, practically none can fully realize its potential based on the intrinsic magnetic properties. We discuss different reasons leading to this limitation, known as the Brown paradox, and discuss some possible ways of overcoming it.

Scarcity of Rare Earth Elements

ChemSusChem, 2013
AbstractRare earth elements (REEs) are important for green and a large variety of high‐tech technologies and are, therefore, in high demand. As a result, supply with REEs is likely to be disrupted (the degree of depends on the REE) in the near future. The 17 REEs are divided into heavy and light REEs. Other critical elements besides REEs, identified by
