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 ...

Free electron X-ray lasers deliver intense, ultrashort pulses of X-rays, which can be used to image nanometer-scale objects in a single shot. When the X-ray wavelength is tuned to an electronic ...

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 ...

Magnetic solids can be demagnetized quickly with a short laser pulse, and there are already so-called HAMR (Heat Assisted Magnetic Recording) memories on the market that function according to this ...

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 ...

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 ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...
