In the late 1800s, the French naturalist Camille Viguier proposed an idea that would be dismissed and forgotten for more than ...

Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in ...

Research groups have made a breakthrough in the field of hard disk drives (HDD) by demonstrating the feasibility of multi-level recording using a three-dimensional magnetic recording medium to store ...

High magnetic fields are a vital tool in many areas of science and technology that impact our everyday lives, from medical diagnostics through magnetic resonance imaging (MRI) to drug discovery ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Laser heating generates a temperature gradient in the MnPt layer, which induces spin currents (green arrows) that are injected into the FePt layer. These spin currents generate spin torque, which ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery" operating ...
