Implications of second harmonic generation for hidden order in Sr₂CuO₂Cl₂
Abstract
Sr₂CuO₂Cl₂ (SCOC) is a model undoped cuprate with I4/mmm crystallographic symmetry, and a simple magnetic space group C_Amca with associated magnetic point group mmm1′. However, recent second harmonic spectroscopy in the antiferromagnetic phase has challenged this picture, suggesting instead a magnetic point group 4/mm′m′ that coexists with the antiferromagnetism and breaks the two orthogonal mirror planes containing the tetragonal c axis. Here, we analyze the symmetry of SCOC in light of the second harmonic results, and discuss possible ground states that are consistent with the data.
