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.
Recently, an inelastic neutron scattering work on the bilayer nickelate La3Ni2O7-δ polycrystal finished by a team from Sun Yat-sen University was published in Science Bulletin. The team employed neutron spectroscopy to study ...
