Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in the final phase have now moved on to launching their satellites within the ...

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 ...

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 ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

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 ...

Magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) at ultrahigh magnetic fields in humans and animals is a uniquely important tool to advance the understanding of function and ...
