- gruturo 9y ago> We have a lot of both fe an ni. Nitpick - "Ni" stands for Nickel. The magnets described in the article are Iron Nitride - that means Iron and Nitrogen (Fe16N2), not Iron and Nickel. Your point stands - Nitrogen is extremely abundant.
- logfromblammo 9y agoBoth of those are actually common enough that if a biological ecosystem ever discovered a competitive advantage for very powerful magnetic crystals, it might have come up with Fe16N2 instead of just the magnetite (Fe3O4) and greigite (Fe3S4) that currently form the basis of biological magnetism. https://en.wikipedia.org/wiki/Magnetosome https://en.wikipedia.org/wiki/Magnetosome
