Permanent Magnetic Materials Without Rare Earth Metals

>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.

I worked as an undergraduate in a academic research lab trying to develop this exact stuff. I would also hazard a guess that we were funded by the same ARPA grant as niron was.

It was a cool concept and got me interested into materials science. Unfortunately the post doc didn’t seem to care too much and the work didn’t go anywhere.

Neat stuff none the less.
