A cobalt-based compound that cools itself to fractions of a degree above absolute zero through magnetic field manipulation ...

Chinese researchers have created a rare-earth alloy that nearly reaches absolute zero, potentially replacing the scarce ...

The fact that an ultrashort laser pulse is capable of demagnetizing a ferromagnetic layer in a jiffy has been well-known since approximately 1996. What we don't yet understand, however, is how exactly ...

Power-supply designers usually like flyback converters to operate in DCM (discontinuous-conduction mode) rather than in CCM (continuous-conduction mode). In DCM, the flyback converter is a first-order ...

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 ...

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 ...

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 ...

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 ...
