A spin model on a honeycomb lattice points to a much sought after type of quantum spin liquid: the Bose metal.

Applying x-ray diffraction microscopy to magnetic systems yields simultaneous spatial and temporal information.

Creating a temperature difference in an arrangement of semiconductors generates a circulating current and a magnetic field, according to simulations. The effect may account for some inefficiency in electronic devices.

A slightly denser version of a transition-metal oxide, with the same chemical composition, has radically different magnetic properties.

Liquid sodium agitated gently in a rotating tank can significantly amplify a magnetic field. The experiment is the first step toward demonstrating a self-sustaining field in a low-turbulence fluid, which may be analogous to Earth’s core.
