Crystal chirality magneto-optical effects in collinear antiferromagnets

The spin chirality, created by magnetic atoms, has been comprehensively understood to generate and control the magneto-optical effects. In comparison, role of crystal chirality that relates nonmagnetic atoms received much less attention. Here, we theoretically discover (CCMO) effects, which depend on structures originates from rearrangement atoms. We show CCMO effects exist in many collinear antiferromagnets, such as RuO$_{2}$ CoNb$_{3}$S$_{6}$, a local global respectively. key character is sign change if reverses. magnitudes spectra can be effectively manipulated reorienting N\'eel vector with help an external electric field, spectral integrals are found proportional magnetocrystalline anisotropy energy.
