摘要
We performed a polarized Raman scattering study of the quasi-one-dimensional superconductor K2Cr3As3. We detect two A'(1) phonons and three E' phonons. One of the A'(1) modes exhibits a nearly temperature-independent Fano line shape. Based on our first-principles calculations, we ascribe this mode to the in-phase vibrations of Cr atoms within one layer. This observation suggests that the magnetic fluctuations in K2Cr3As3 are coupled to the electronic structure via the lattice.
