Magneto-optical spectra of an organic antiferromagnet as a candidate for an altermagnet

We have measured the magneto-optical Kerr effect (MOKE) in an orthorhombic organic antiferromagnet κ-(BEDT-TTF)_{2}Cu[N(CN)_{2}]Cl (κ-Cl), which is a candidate for an altermagnet. From the Maxwell equations, we derived matrix-type general formulae describing the optical propagation and reflection fo...
