| description | The discovery of a giant anomalous Hall effect (AHE) and its novel mechanism
holds significant promise for advancing both fundamental research and practical
applications. Magnetic kagome lattice materials are uniquely suited for
studying the AHE due to their interplay between electronic structure, topology,
and magnetism. However, the geometric frustration inherent in kagome lattices
often limits the configuration and tunability of magnetic order. Here, we
present a new design strategy for kagome-lattice materials with emergent
magnetism, exemplified by the magnetic kagome metal TbTi$_3$Bi$_4$, which
features interwoven magnetic Tb zigzag chains and non-magnetic Ti kagome
bilayers. This material exhibits a record-high anomalous Hall conductivity
(AHC) of 10$^5$ $\Omega^{-1}$ cm$^{-1}$. Spectroscopy measurements reveal a
large band folding gap observed via angle-resolved photoemission spectroscopy,
coexisting spin-density-wave (SDW) order detected through spin-polarized
scanning tunneling spectroscopy, and a spiral magnetic order with large
magnetic moments identified by neutron diffraction. These findings highlight a
strong electron-magnetic coupling between itinerant charges and ordered
magnetic moments, offering a spectroscopic explanation for the giant AHC in
TbTi$_3$Bi$_4$. This work establishes a pathway for innovative material design
strategies, unlocking new possibilities for future exploration and applications
in quantum and spintronic technologies. |
