A microscopic magnetite fossil (left) discovered in sediment below the North Atlantic, seen using X-ray microscopy; the fossil?s magnetic configuration, with magnetic moments swirling around a central ...

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional systems. In conventional antiferromagnets, the ...

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, ...

Scientists for the Event Horizon Telescope collaboration say the magnetic structure of the Milky Way’s central Sagittarius A* black hole is “strikingly similar” to the bigger singularity in the middle ...

Conventional hard disks are based on ferromagnets—materials in which the magnetic dipoles, or spins, associated with each atom all point in the same direction. This alignment gives the material a net ...

Scientists at the U.S. Naval Research Laboratory (NRL) have identified the true source of a magnetic effect seen in the ...

Figure (a) shows the crystal and spin structure of MnTe, with manganese atoms in red and blue and tellurium atoms in yellow. Figure (b) illustrates how circularly polarized light produces distinct ...
