The spin-phonon coupling coefficients discussed in the previous section have been used together with Eq. 6 to simulate the longitudinal relaxation time τ of three different systems: one single electronic spin, one electronic spin interacting with the V nuclear spin, and two interacting electronic spins.

Spin-Phonon Coupling in Ferromagnetic Monolayer Chromium.

Calculation of spin-phonon coupling constants for the vibra-tional modes shows that the first vibrational mode, despite having a low spin-phonon constant, is the most efficient process for the spin relaxation at low temperatures. In such conditions, vibrational modes with higher spin-phonon cou-pling constants are not populated. Additionally. Inelastic neutron scattering measurements have been performed on YMnO3, aiming to study the interplay between spin and lattice degrees of freedom in this hexagonal multiferroic material.

The naturally weak spin-orbit coupling in Graphene can be largely enhanced by adatom deposition (e.g. Weeks et al. Phys. Rev. X 1, 021001 (2011)). However, the dynamics of the adatoms also induces a coupling between phonons and the electron spin. Using group theory and a tight-binding model, we systematically investigate the coupling between the low-energy in-plane phonons and the electron. In these compounds, spin–phonon coupling (SPC) typically plays a crucial role in magnetic fluctuations, magnon dissipation, and ultimately establishing long-range ferromagnetic order.
