Magnetism as a research area investigates phenomena arising from moving charges and intrinsic magnetic moments of particles, with emphasis on spin, orbital angular momentum, and their collective behavior in materials. It encompasses fundamental studies of exchange interactions, magnetic ordering (ferromagnetism, antiferromagnetism, ferrimagnetism, spin glass states), and quantum magnetism, as well as the characterization of magnetic domains, anisotropy, and spin dynamics. The field integrates theory, simulation, and experiment to understand and engineer magnetic materials for applications in spintronics, data storage, magnonics, quantum information, and magnetic sensing, often leveraging advanced techniques such as neutron scattering, magnetic resonance, and nanoscale magnetic imaging.
Magnetic fields are generally known to destroy superconductivity in a material. However, in exceptional cases, they can lead to what is known as "re-entrant superconductivity"—where superconductivity disappears as expected, ...

Scientists can learn a lot about a quantum material by watching how it responds to light. In magnetic semiconductors, one especially useful messenger is the exciton: a pairing of a negatively charged electron and the positively ...
