Chinese researchers have engineered a scanning tunneling microscope (STM) tip using α-Bi₄Br₄ single crystals to detect altermagnetism, a rare magnetic state without net magnetization, in 2D materials. By leveraging the quantum spin Hall effect and helical edge states, this novel probe resolves atomic-scale spin-dependent electronic behaviors that conventional tips miss. The breakthrough links local atomic structure to specific scattering patterns, offering new tools for probing exotic quantum phases in condensed matter physics.
