Adiabatic demagnetization is an efficient technique for cooling solid samples by several orders of magnitude in a single cooling step. In gases, the required coupling between dipolar moments and ...

Irradiating a ferromagnet with a femtosecond laser pulse is known to induce an ultrafast demagnetization within a few hundred femtoseconds. Here we demonstrate that direct laser irradiation is in fact ...

The Einstein-de Haas effect, first demonstrated more than a century ago, provides an intriguing link between magnetization and rotation in ferromagnetic materials. Researchers have now found that the ...

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 use of permanent magnets is increasing in modern electrical machines because of the need for reduced size and higher performance. An important consideration in electrical machine design is the ...
