Spin wave spectroscopy is a technique employed in condensed matter physics to study the collective excitations of electron spins, known as spin waves, within magnetic materials. By using various experimental methods such as neutron scattering or Brillouin light scattering, spin wave spectroscopy measures the energy and momentum of these spin waves, providing insights into the magnetic properties, interactions, and dynamics of the material's spin system. This approach helps researchers understand phenomena like magnetic ordering, anisotropy, and spin transport, with applications in fields ranging from magnetism-based electronics (spintronics) to fundamental studies of magnetism.
