    • The SLR rate shown in Fig. was calculated numerically, solving a quantum master equation including phonon-induced transitions between energy eigenstates. The spin-phonon interaction Hamiltonian was 3 B20 { (xz + ωxz )- [ Sx Sz + Sz Sx ] + ( yz + ωyz )- [ Sy Sz + Sz Sy ] }, where iz and ωiz represent phonon-induced strains and rotations, respectively. The speed of sound cs =2.3× 105 cm/s was determined from the Debye temperature θD =57K extracted from heat-capacity experiments (Ref.).
