WebJun 1, 2024 · Bosonic Dirac materials are testbeds for dissipationless spin-based electronics. In the quasi two-dimensional honeycomb lattice of CrX3 (X = Cl, Br, I), Dirac magnons have been predicted at the crossing of acoustical and optical spin waves, analogous to Dirac fermions in graphene. WebWe carried out a systematic theoretical study on how spin affects the phononic properties of CrI 3 monolayers. We find that the frequencies of two infrared-active (IR) modes are … people v. buckhalter

Bulk CrI3 crystals were grown by direct vapour transport and exfoliated onto 90-nm SiO2/Si substrates. Using the optical contrast between the flakes and the substrate, monolayer and bilayer flakes of CrI3 were identified and encapsulated between two 20–30-nm-thick hexagonal boron nitride (hBN) … See more RMCD measurements of CrI3 samples were performed in a cold-finger cryostat capable of reaching temperatures down to 15 K and applying magnetic fields up to … See more In monolayer CrI3, the Cr3+ ions form a honeycomb structure with two inequivalent sites (denoted by A and B) per unit cell. Consequently, the magnon … See more WebJan 31, 2024 · Magnons dominate the magnetic response of ferromagnetic two-dimensional crystals such as CrI3.
