Mapping the Phase Space of Fe-Ni alloys in Meteorites: revealing the chemical and crystallographic complexity of REE-free magnet analogues

Rare-earth permanent magnets play a critical role in green technologies such as wind turbines and electric
vehicles. These elements are mainly sourced from a limited number of countries, many of which suffer
from complex political situations. A desire for secure and ethical materials drives a strong global interest
in developing low-cost…
