Low-temperature demagnetization and ice-pressure demagnetization in magnetite and haematite [PDF]
Geophysical Journal International, 1994 SUMMARY Low-temperature demagnetization (LTD) is confirmed as an effective method of removing soft (low coercivity) components of remanence in magnetite-bearing specimens by passing the magnetite through its low-temperature transition (?130 K). Haematite has its low-temperature transition at approximately 258 K.

Ultrafast Transitions in X‐Ray Irradiated Solids
Contributions to Plasma Physics, EarlyView.ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Responsive Materials, EarlyView.We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...
