Andrew Kuchling@Merovius Not uncommon on Wikipedia, where various editors add facts over time, sometimes without reading the existing page too closely.
I found this EU page https://rmis.jrc.ec.europa.eu/rmp/Dysprosium which gives a 2021 figure of 3126 tons produced, 40% of which was from China, 31% from Myanmar, and 20% from Australia.
Do I have to look at & update all of the rare-earth pages now? 😨 Maybe tomorrow!

At this extremely close proximity, the atoms’ natural magnetic interactions were significantly enhanced; 1000x stronger than if positioned 500nm apart. The team observed that these interactions resulted in two novel quantum phenomena: collective oscillation, in which one layer’s vibrations caused the other layer to vibrate in sync; and thermalization, in which one layer transferred heat to the other, purely through magnetic fluctuations in the #dysprosium atoms.
Physicists arrange atoms in extremely close proximity
MIT physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate — a key building block for a new type of quantum computer.

Svenssons NyheterSällsynta jordartsmetaller har ökat kraftigt i bilar
Sällsynta jordartsmetaller som neodym och dysprosium har ökat enormt i nya bilar sedan 2006, med 400 respektive 1 700 procent. Men återvinningen är liten och metallutbudet räcker inte för att möta efterfrågan på bland annat elbilar, en

Nafnlaus 🇮🇸 🇺🇦@riskable My focus is on the #EV space. But temperature matters there too, because #neodymium magnets start to lose field strength in the range of temperatures motors actually experience (~80°C). So you have to use higher amounts of #dysprosium, which means even higher cost & somewhat lower nominal field strengths. So #tetrataenite could be a really good fit, IF the achievable field strengths can approach the theoretical.
Need to watch this space, as I have investments in some rare earth plays.
