Abstract

Read online

Whether the electronic nematicity is related to electronic pairing in strongly hole-doped iron-based superconductors remains controversial. Here, the authors perform transport measurements on AFe2As2 (A = K, Rb, Cs) superconductors under elastic strain, and find no indication of a nematic ordered state.
