Orbital-loop-current-induced magnetic structure in a kagome superconductor
The charge-density-wave (CDW) order in the recently highly-topical kagome superconductor AV3Sb5 (A=K, Rb, Cs) is suggested to be unconventional in nature. Intriguingly, a chiral flux phase consisting of orbital loop current was proposed theoretically, supported by the experimental observation of field-tunable charge chirality and spontaneous time reversal symmetry breaking. Nevertheless, the orbital magnetic structure induced by the loop current is yet to be determined. We thereby propose to study the orbital magnetic order and its interplay with CDW transition in RbV3Sb5 using uniaxial polarization analysis, which was previously adopted to be an effective method uncovering the orbital loop current in the pseudo-gap state of cuprate superconductors. The success of this experiment will provide crucial information on the unusual loop current state, shedding lights on the structure and microscopic origin of the exotic CDW order in AV3Sb5.
