Extended Data Fig. 1: Additional MCD data and MCD spectra.
From: Asymmetric magnetic proximity interactions in MoSe2/CrBr3 van der Waals heterostructures

a, Hysteresis loops of the MCD signal from the MoSe2/CrBr3 heterostructure, acquired at the B-exciton transition of the MoSe2 monolayer (photon energy = 1.83 eV; cf. Fig. 1e of the main text). b, MCD spectra of an isolated ‘control’ MoSe2 monolayer, compared with the MCD spectra of the MoSe2/CrBr3 heterostructure, at 4 K. Each spectrum was obtained after the CrBr3 was magnetized by applied magnetic fields (cf. Fig. 1d of the main text).
