【 摘 要 】
We critically review the experimental determination of the nonreciprocal x-ray gyrotropy in the monoclinic antiferromagnetic insulating phase of V2O3, highlighting some of its paradoxical consequences. We also note the apparent absence of a normal (nonmagnetic) linear dichroism in the data, and speculate on the possible reasons for it. Given the importance of the implications of a nonreciprocal effect for the physics of V2O3, one of the paradigmatic strongly correlated system, we point up the need for at least repeating the experiment under better controlled conditions and suggest possible tests for establishing unambiguously its existence.
