(a) Raman spectra taken in both linear parallel and crossed channels in monolayer CrI₃ at 15 K and 0 T. Polar plots of polarization dependent Ag mode intensity (∼129 cm^–1) at 60 and 15 K, above and below the magnetic onset temperature T_C = 45 K, respectively. (b) Raman spectra of 2L CrI₃ at 15 K and at 0 and 1.5 T in linearly parallel and crossed channels. Panels (a, b) adapted with permission from ref (221). Copyright 2020 Springer Nature. (c) Raman spectra of 2L CrI₃ at 1.7 K and at 0 T and −1 T in linearly parallel and crossed channel. Adapted with permissions from ref (222). copyright 2020 American Chemical Society. (d) Raman spectra of 10L CrI₃ at 9 K and at selected magnetic fields. Adapted with permission under a Creative Commons CC BY license from ref (223). Copyright 2020 Springer Nature.
