We have seen that, in nonrelativistic quantum mechanics, the angular momentum operator is the generator of rotations and commutes with the Hamiltonians of rotationally invariant (i. e., spherically symmetric) systems1. It thus plays a special role for such systems. For this reason, as a prelim...
Harnessing both spin and orbital angular momentum, electrons offer two powerful properties for advancing spintronics and orbitronics—fields poised to revolutionize information technology. This holds enormous potential for breakthroughs such as ultrahigh-density memory and precision quantum sensing. The discover...
Interfacial Dzyaloshinskii-Moriya interaction (DMI), a short-range anti-symmetric exchange interaction that promotes chirality of nanoscale spin textures, has become a foundational aspect of spintronics research1,2,3,4,5. A strong DMI can compete with ferromagnetic exchange interaction and perpendicular ...
We show that this can result in efficient generation and transport of electronic orbital angular momentum by magnons, thus opening the road to combining the functionalities of magnonics and orbitronics to their mutual benefit in the realm of spintronics applications.#The chiral spin texture hosted by...

The orbitally-dependent exchange was shown to lead to an anomalously strong magnetic anisotropy that can be considered as a main physical manifestation of the unquenched orbital angular momentum in metal clusters of orbitally-degenerate ions. The theoretical background is illustrated by the following ...
