Gyrotropic Fingerprints of Magnetic Topological Insulator-Unconventional Magnet Interfaces
This paper proposes that the displacement component of the linear intrinsic gyrotropic magnetic response in magnetic topological insulator-unconventional magnet interfaces serves as a high-fidelity, experimentally measurable fingerprint for identifying and distinguishing the symmetry of unconventional magnetic orders through its unique angular harmonics and sign-reversal patterns.
