英文摘要
The PI will carry out a multifaceted suite of experiments to investigate the physical links among local energy minimum (LEM) domain states. LEM-LEM transitions, and thermoremanent magnetization (TRM) in magnetite, titanomagnetite, and pyrrhotite. This work would utilize magnetic domain observations coupled with measurements of TRMs in single particles.
