I'll be reviewing this article, and will be basing my evaluation on previous GARs (1 and 2) and adding additional comments.ChopinChemist^Talk? 03:54, 29 September 2026 (UTC)

Thanks for taking up the review! ¹⁴¹Pr -_\contribs/- 15:53, 29 September 2026 (UTC)

Well-written

a. prose

Thin films 45 nm thick have been reported to order ferromagnetically below approximately 19 K This could be better worded to "Thin NdO films 45 nm thick show ferromagnetic properties at approximately 19K"

 Done - I've changed the sentence to "Thin NdO films 45 nm thick have been reported to become ferromagnetic below about 19 K." ¹⁴¹Pr -_\contribs/- 20:02, 30 September 2026 (UTC)

Verifiable with no original research

Physical properties

• It melts at approximately 1,024 °C (1,875 °F) and boils at 3,074 °C (5,565 °F).[11] Source [11] is dead, could replace with this url but I don't recommend due to the conversion error (melting point 10218.5 °C!). I suggest replacing with CRC Handbook or Arblaster in the infobox for the melting point. Furthermore, if source [11] is replaced by the url above, other issues persist:

• On heating at atmospheric pressure, this structure transforms into a body-centered cubic phase at about 863 °C (1,585 °F).[15][11] The Los Alamos National Laboratory URL would not support this claim but citation [15] does.
• The metal tarnishes in air. Its surface oxide can flake away, exposing fresh metal and allowing oxidation to continue.[11] and this section Neodymium is a constituent of mischmetal, a mixture of rare-earth metals whose traditional composition contains about 18% neodymium.[11]... Neodymium salts are used to color enamels.[11] The Los Alamos National Laboratory URL above would not support these claims.
• Although the element had been identified in its compounds, neodymium metal was not isolated in relatively pure form until 1925.[11] Haynes 2016 would be a better source for this claim

TLDR: The Los Alamos URL should be replaced.

Uses

• Neodymium-doped glass slabs used in high-energy laser systems for inertial confinement fusion research. This detail should be cited given its inclusion in the lead.

Chemical properties

• The source Webelements.com [22] should be removed as the link is no longer active. I will find sources then suggest a replacement later, but you could look at Advanced Inorganic Chemistry by Dr. Cotton and Dr. Wilkinson

 Done - I’ve replaced the WebElements citations with other citations including Cotton et al. and Ganjali et al. ¹⁴¹Pr -_\contribs/- 18:37, 29 September 2026 (UTC)

Permanent magnets

• Ref 82-84 in Other audio applications include headphones[82] and magnetic pickups for guitars and bass guitars.[83][84] should be replaced with more reliable sources per WP:VENDOR. A suggested source to replace 82 is Bünzli & Mcgill 2018, p. 43 in Ullmann's encyclopedia:

Bünzli, Jean‐Claude G.; Mcgill, Ian (2018). "Rare Earth Elements". Ullmann's Encyclopedia of Industrial Chemistry. Weinheim: Wiley-VCH. doi:10.1002/14356007.a22_607.pub2. ISBN 978-3-527-30673-2.

 Done - I’ve replaced the vendor references with independent sources. The headphone claim now cites Bünzli & McGill, and I changed the guitar-pickup wording to match an IEEE source; I have removed the bass-guitar example as I couldn't find an independent and reliable ref for it. ¹⁴¹Pr -_\contribs/- 18:05, 29 September 2026 (UTC)

Source spot check

[12] Y [13] Y [26] This source doesn't provide a strong support for the claim Some neodymium compounds change their apparent color under different types of illumination [29]Y [36]Y [60]Y [113]Y
