Nematic susceptibility in heavily hole-doped iron based superconductors — •Franz Eckelt1, Xiaochen Hong1, Vilmos Kocsis2, Vadim Grinenko2, Chul-Ho Lee3, Bernd Büchner2, and Christian Hess11Bergische Universität Wuppertal, 42097 Wuppertal, Germany — 2Leibniz-Institute for Solide State and Materials Research (IFW-Dresden), 01069 Dresden, Germany — 3National Institute of Advanced Industrial Science and Technology (AIST), Tsukuba, Ibaraki 305-8568, Japan

We investigate the elastoresistivity of the heavily hole doped iron-based superconductor Ba1−xKxFe2As2 in the range x= 0.68 - 0.98 using a piezoelectric measurement technique. We observe a divergent increase in elastoresistance along the [100] direction during cooling for all samples studied so far. We discuss our findings in terms of nematic fluctuations and Fermi surface effects in the vicinity of a Lifshitz transition.
