Researchers analyzed 28 Ryugu asteroid samples and found preserved magnetic signals that record early solar system magnetic fields and water-driven alteration on its parent body.

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

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 ...

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

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

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 ...

New measurement system captures complete magnetic hysteresis loops at megahertz frequencies, closing a key gap in ...

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 ...

The best candidate for next-generation magnetic devices—technology that can power, store, sense or transport information—may be, counterintuitively, antiferromagnets. Today, the most widely used ...

Scientists studying lunar samples have finally resolved a decades-long debate about the Moon’s ancient magnetic field.

By applying the Kerr effect, Kerr microscopy facilitates the analysis of magnetic domains in steel alloys, supporting ...

In this study, NRM measurements suggest that the observed characteristics of Ryugu particles is a chemical remanent ...
