Magnetic systems, as physical systems, are assemblies of magnetic moments (spins or orbital moments) interacting via exchange, dipolar, or relativistic (e.g., Dzyaloshinskii–Moriya) interactions, often modeled on lattices or in continuum field theories. They encompass ferromagnets, antiferromagnets, ferrimagnets, spin glasses, and frustrated magnets, and are described microscopically by Hamiltonians such as the Heisenberg, Ising, or Hubbard models. Key properties include magnetic ordering, phase transitions, domain formation, and collective excitations (spin waves, magnons). Magnetic systems are central to studying critical phenomena, symmetry breaking, and quantum many-body effects, and underpin technologies in data storage, spintronics, and magnetic sensing.
RIKEN physicists have discovered for the first time why the magnitude of the electron flow depends on direction in a special kind of magnet. This finding could help to realize future low-energy devices.
