New Nanomaterials Created Using Superatomic Magnetic Clusters.
Aug 18 2022Reviewed by Bethan Davies Magnetic materials are employed in a variety of devices, including motors, sensors, cell phones, and data storage. As technology becomes smaller and smaller, researchers are constantly hunting for new magnetic particles.
Superatoms are endowed with unusual characteristics as a result. The new nanoparticle has two separate electronic subshells that are each packed with 57 and 50 electrons, respectively. This dual shell filling generates the energy stability required for the synthesis of superatoms as well as the stable magnetic orderings that give superatoms their special characteristics.
Summary The classical mechanisms by which spin magnetic moments develop in atoms and ferromagnetic metals are described by Hund’s rule in atomic physics and by the Stoner model in solid-state physics. Valence electrons evade pairing in both models by occupying half-filled orbitals, which raises the exchange energy and reduces Coulomb repulsion.
This mechanism, which functions exclusively at the nanoscale, is strikingly similar to the mechanism driving magnetic semiconductors. The production of high spin states in clusters is generally prevented by Jahn-Teller distortions, but the dual subshell filling method produces great electronic stability and a significant magnetic moment.
