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.
A difficult-to-describe nanoscale object called the magnetic skyrmion might one day yield new microelectronic devices that can do much more—for example, massive data storage—all while consuming much less power.

Moiré superlattices are materials consisting of two layers stacked on top of each other with either a small rotational misalignment or a lattice mismatch between them. The Kondo lattice model, on the other hand, describes ...
When something draws us in like a magnet, we take a closer look. When magnets draw in physicists, they take a quantum look. Scientists from Osaka Metropolitan University and the University of Tokyo have successfully used ...
