Thermomagnetic recording fidelity of nanometer-sized iron and implications for planetary magnetism [Earth, Atmospheric, and Planetary Sciences]

Paleomagnetic observations provide valuable evidence of the strength of magnetic fields present during evolution of the Solar System. Such information provides important constraints on physical processes responsible for rapid accretion of the protoplanetesimal disk. For this purpose, magnetic recordings must be stable and resist magnetic overprints from thermal events and...
