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.
Everybody makes mistakes. Biology is no different. However, living organisms have certain error-correction mechanisms that enable their biomolecules to assemble and function despite the defective slough that is a natural ...
