Title

Temperature dependence of magnon and phonon in Kagome metal FeGe

Abstract

The antiferromagnetic (AFM) kagome metal FeGe exhibits a novel charge-density-wave (CDW) transition at T_{CDW} = 100K well below the Neel temperature (410K). More interestingly, the CDW phase can enhance the AFM peak intensity by presumably increasing the Fe ion moment. This makes FeGe the first example of CDW-enhanced magnetism in strongly correlated systems, offering a new platform for exploring emergent phenomena in strongly correlated materials. In particular, it is important to determine the role of magnon and electron-phonon coupling in the mechanism of CDW. Therefore, we propose to perform detailed temperature dependence measurements on FeGe magnon and phonon spectrum.
