Extended Data Fig. 6: Magnetic circular dichroism (MCD) measurements comparing 1L α-RuCl3 and 1L CrBr3.
From: Magnetic anisotropy reversal driven by structural symmetry-breaking in monolayer α-RuCl3
(a): \({{{\mathrm{{\Delta}}}MCD}} = {{{\mathrm{MCD}}}} - {{{\mathrm{MCD}}}}(0{{{\mathrm{T}}}})\) for 1L α-RuCl3 at 3.5 K and 1L CrBr3 at 5 K between ±70 mT. The data for 1L CrBr3 is reproduced from previous work in ref. 27. (b): MCD data for 1L α-RuCl3 at 3.5 K between ± 8 T.
