The resistive anisotropy of FeSe in the nematic state — •Clifford Hicks1,2, Jack Bartlett2, Alexander Steppke2, Suguru Hosoi3, Takasada Shibauchi4, and Andrew Mackenzie21University of Birmingham, U.K. — 2Max Planck Institute for Chemical Physics of Solids, Dresden — 3Osaka University, Japan — 4University of Tokyo, Japan

We employed strain tuning to adjust the degree of twinning of samples of FeSe. By doing so, we were able to measure the resistive anisotropy in the nematic state. The resistive anisotropy of the nematic state, along with the dependence of the resistivity and the superconducting critical temperature on biaxial strain suggest a strong role for the yz orbital in electronic scattering in FeSe.
