Following on from insights gleaned from iron meteorites, Claire Nichols explains why tetrataenite, with its unique magnetic properties, could be key for future renewable energy technologies.doi:10.1038/s41561-023-01141-2Nichols Claire I. O.
When the Ni content passes 30%, kamacite is no longer stable above room temperature. However, taenite becomes ferromagnetic in this range. The iron in lunar rocks is seldom Ni-rich unless it is of meteoritic origin. Magnetic properties of Ni–Fe in different classes of meteorites and syntheti...

Nanoscale intergrowths of tetrataenite have been shown to carry records of paleomagnetic fields, although the effect of magnetostatic interactions on their magnetic remanence acquisition remains to be fully understood. Tetrataenite can also occur as isolated, non‐interacting, nanoscale grains in many ...
The mineral has drawn much attention of the scientific community because of its superb magnetic properties, which may make the phase an alternative to the REE-based permanent magnets. Barring only a few passing mentions, the mineral has never been described from any ...

The natural remanent magnetization (NRM) of tetrataenite-rich meteorites is extremely stable against AF-demagnetization and other magnetic disturbances because of the high magnetic coercivity of tetrataenite. The breakdown processes of ordered tetrataenite structure by heat treatments are experimentally ...
