The future development of functional magnetic devices based on ultrafast optical manipulation of spins requires an understanding of the depth-dependent spin dynamics across the interfaces of complex ...

Geologists discovered ancient rocks in Greenland that preserve the oldest known traces of Earth’s early magnetic field.

The field of ultrafast magnetism explores how flashes of light can manipulate a material's magnetization in trillionths of a second. In the process called all-optical switching (AOS), a single laser ...

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 ...

The left side of the figure schematically shows how a series of two-dimensional scanning electron microscopy images of an ultrafine-grained Nd-Fe-B magnet were transformed into a three-dimensional ...

Heat is the energy of motion of tiny particles, the vigorous dance of the atoms and molecules that constitute matter. When matter is chilled, the dance becomes torpid. At Absolute Zero ( —273.13 ...
