The intertwining between spin, charge, and lattice degrees of freedom can give rise to unusual macroscopic quantum states, including high-temperature superconductivity anomalous Hall effects. Recently, a charge density wave (CDW) has been observed in the kagome antiferromagnet FeGe, indicative possible physics. An outstanding question is that whether magnetic correlation fundamental for spontaneous spatial symmetry breaking orders. Here, utilizing elastic high-resolution inelastic x-ray...

AFM transition temperatures...
Abstract Exotic quantum states arise from the interplay of various degrees freedom such as charge, spin, orbital, and lattice. Recently, a short-ranged charge order (CO) was discovered deep inside antiferromagnetic phase Kagome magnet FeGe, exhibiting close relationships with magnetism. Despite extensive investigations, CO mechanism remains controversial, mainly because behavior hinders precise identification superstructure. Here, combining multiple experimental techniques, we report...

Magnetotransport properties, nonzero Berry phase, small cyclotron mass indicate the presence of fermions. Angular-dependent magnetoresistance indicates possible quasi-two-dimensional Fermi surface, whereas deviation from nontrivial phase expected for states suggests contribution parabolic bands at level or spin-orbit coupling.
