The discovery of femtosecond laser-induced demagnetization in ferromagnetic nickel in 1996 marked the birth of ultrafast spin dynamics research. This phenomenon not only provides new insights into the ...

Scientists have succeeded in simulating the magnetization reversal of Nd-Fe-B magnets using large-scale finite element models constructed based on tomographic data obtained by electron microscopy.

Atomic scale copper rich layers inside rare earth magnets suppress demagnetization, improving strength, stability, and efficiency in motors and generators. (Nanowerk News) Rare-earth magnets are ...

For the first time, researchers have mapped how the boundaries of magnetic nanostructures behave on extremely short timescales. The work of physicist Johan Mentink of Radboud University shows that ...

The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

The left side of the figure schematically shows how a series of two-dimensional scanning electron microscopy images of an ultrafine-grained Nd-Fe-B magnet were transformed into a three-dimensional ...
