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 ...
A research team led by Prof. Sheng Zhigao from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Prof. A.V. Kimel from Radboud University, has ...
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 ...
Rare earth magnets are a crucial component of electric motors in an electric vehicle (EV). According to IDTechEx, rare earth permanent magnet motors have retained a greater than 75% market share since ...
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 ...
