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.

Researchers at Ames National Laboratory are advancing the discovery of materials for rare-earth-free permanent magnets by ...

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 ...

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 ...

A research team led by the Institute of Plasma Physics, Chinese Academy of Sciences, has developed an all-superconducting magnet system that reached a steady-state magnetic field of 35.1 tesla and ...
