Spin-orbit coupling: an endless source of exotic phenomena in 2D magnets
Silvia Picozzi, D'Annunzio University
During the last decades, the spin-orbit coupling (SOC) has played an increasingly crucial role in condensed matter physics, thanks to its relevance as a rich microscopic mechanism from the fundamental point of view and as a driving force for innovative spintronic applications on the technological side. Combined with the global thrust towards miniaturization and with the ubiquitous research in two-dimensional (2D) materials, the talk will focus on the modelling of 2D magnets with emphasis on SOC-induced effects. In particular, I will focus on the magnetic and ferroelectric properties of transition-metal monolayers (mostly halides) and discuss the role of SOC in the magnetoelectric coupling. The reports of multiferroicity in NiI2 layers [1], obtained via a joint theory-experiments approach down to the single-layer limit, show the potentiality of cross-coupling phenomena in van der Waals magnets. If time permits, other recent examples – such as SOC-induced effects in CrSBr monolayers - will be discussed.
