Distinct magneto-Raman signatures of spin-flip phase transitions in CrI3

Distinct magneto-Raman signatures of spin-flip phase transitions in CrI3

Thin samples CrI3 exhibit a phase transition under an applied magnetic field from layered antiferromagnetism to ferromagnetism. Here the authors observe an associated abrupt change in the magneto-Raman spectra, illustrating the sensitivity of Raman spectra to magnetic ordering.
