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.
Numerous memory types for computing devices have emerged in recent years, aiming to overcome the limitations imposed by traditional random access memory (RAM). Magnetoresistive RAM (MRAM) is one such memory type which offers ...
