A.A. Ovchinnikov, M.Ya. Ovchinnikova
TL;DR
This paper discusses the potential for observing time reversal symmetry breaking in the normal state of Sr2RuO4 through ARPES experiments, based on a predicted spiral spin structure due to nesting.
Contribution
It proposes a method to detect possible time reversal symmetry breaking in Sr2RuO4 using ARPES with circularly polarized photons, based on a theoretical spiral spin structure.
Findings
The normal state of Sr2RuO4 may have a spiral spin structure.
ARPES with circular polarization could observe this structure.
The study suggests a new way to detect symmetry breaking in this material.
Abstract
A spiral spin structure with a nesting vector is expected to be the ground normal state of . It might be observable with use of the ARPES method with circularly polarised photons desighned by A.Kaminsky et al. (cond-mat/0203133).
