neodymium (countable and uncountable, plural neodymiums)

1. A chemical element (symbol Nd) with an atomic number of 60: a hard, slightly malleable silvery rare earth metal that quickly tarnishes in air and moisture.
   • 2004, Richard Fortey, The Earth, Folio Society, published 2011, page 63:

     Other rare elements, like neodymium, exist in more than one isotopic form, the ratios of which can provide a measure of the depth from which the flow material may ultimately have been derived.

   • 2025 July 18, Timothy McLaughlin, “A Rebel Army Is Building a Rare-Earth Empire on China's Border. The Kachin Independence Organization fought for decades in obscurity. Now it's supplying essential minerals to manufacturers around the world”, in Bloomberg Businessweek‎^[1], archived from the original on 18 July 2025:

     The most important application of dysprosium and terbium, which belong to a subgroup known as the heavy rare earths, is in devices called neodymium boron magnets, or neo magnets for short.

   • 2025 August 30, Gillian Tett, “America’s new ‘patriotic’ capitalism”, in FT Weekend, London: The Financial Times Ltd., →ISSN, →OCLC, page 7:

     But the government also gave MP Materials a decade-long guaranteed price floor for its products, such as the rare earths neodymium-praseodymium, at twice recent market rates (leaving aside the fact prices have soared this week as MP Materials has cut ties with China).

2. (countable) A single atom of this element.
