- Topological insulators (TIs) are a new state of matter giving rise to exotic physical phenomena and material properties, and therefore strategically important for ICT. Direct determination of the surface state of TIs is critical for the fundamental understanding, but has been a long-standing challenge in TI research. This work demonstrates the first unambiguously spectroscopic evidence of enhanced surface magnetism in magnetic TIs. We defined and validated a new experimental method to determine their magnetic ground state in a surface-specific manner. The work has important implications in band engineering and set a standard approach to determine surface magnetism.
