Comment on "Distinct spin–lattice and spin–phonon interactions in monolayer magnetic CrI" by L. Webster, L. Liang and J.-A. Yan, Phys. Chem. Chem. Phys., 2018, 20, 23546. Issue 29 (14th July 2022) - Liu, Y. C.
Abstract : We point out four mistakes in the symmetry classification of vibrational modes of the CrI3 monolayer at the Γ point in Webster et al. 's paper [ PCCP, 2018, 20, 23546]. The discrepancy of Raman activity of A2g mode as well as the misidentification of two optical modes A1u and A2u have been clarified.
