Rare Earth Compounds. I. Rare Earth Polysulfides

Inorganic Chemistry, 1964
The polysulfides of Tb, Ho, and Er were prepared for the first time. New information was obtained for a number of rare earth polysulfides. A larger phase region with a more complex crystal structure was found to exist. Sulfur to metal atom ratios of 1.7 to 2.0 were found for the lightest rare earths and 1.7 to 1.8 for the heavier rare earths.

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.
