@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.
