Recent progress in materials science has led to the creation of new magnetic materials in which the magnetism follows complex patterns. The formation of these patterns depends on a phenomenon called spin-orbital coupling. Because they can be manipulated by electric currents and temperature changes, materials exhibiting these interesting magnetic patterns may have applications in magnetic memories and logic devices.
One of the oldest and most studied materials in all of physics and materials science has been shown to display magnetism when illuminated with a certain type of light.
Superconductors and magnetic fields do not usually get along, but a research team led by a Brown University physicist has produced new evidence for an exotic superconducting state that can indeed arise when a superconductor is subject to a strong magnetic field. Their results could enable scientists to develop materials for more efficient memory storage, and even help to explain the behavior of distant astronomical objects called pulsars.
