Of the papers based on this thesis work, this one has the most comparisons to other magnet families: "Directly obtained τ-phase MnAl, a high performance magnetic material for permanent magnets" https://www.sciencedirect.com/science/article/pii/S0022459616300548?via%3Dihub https://www.sciencedirect.com/science/article/pii/S002245961... These magnets aren't as strong (in terms of energy product) as those based on rare earth elements, but they are stronger than ferrite permanent magnets. They are also more tolerant of high temperatures than neodymium based magnets.

>They are also more tolerant of high temperatures than neodymium based magnets. Ooh, that's exciting. The nickel coatings on NdB magnets is nicely conductive, but they are difficult to solder to without destroying their magnetism. One neat trick is that neodymium magnets seem to tolerate extreme temperatures better if you cover as much of them as possible with slabs of ferrous metal during the time that they are at an elevated temperature.
