A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

Paleomagnetic analysis of 28 Ryugu asteroid particles reveals stable magnetization acquired within millions of years of solar ...

Ferromagnets are magnetized permanently in domains that are either parallel or antiparallel to the easy axis directions. The magnetization direction can be manipulated using external magnetic fields ...

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread ...

Scientists at the University of Tokyo have captured something never seen before: a frame-by-frame view of how electron spins ...

Suppression of intervalley scattering observed in the QPI pattern. Credit: Nature Physics (2025). DOI: 10.1038/s41567-025-02864-2 Altermagnets, which exhibit momentum-dependent spin splitting without ...

High-frequency magnetic characteristics are essential for improving the efficiency, miniaturization, and operating frequency ...

Samples from Ryugu, a small, near-Earth asteroid, preserve natural remanent magnetization (NRM) from the early history of the solar system. However, despite multiple studies, there is currently no ...

To magnetize an iron nail, one simply has to stroke its surface several times with a bar magnet. Yet, there is a much more unusual method: A team has discovered some time ago that a certain iron alloy ...
