The effect of non-superconducting dopants (Mn, V, Cr and Cu) on the nematic fluctuations in iron-based superconductors

Yanhong Gu, Yuan Wei, Dongliang Gong +14

We have systematically studied the nematic susceptibility in non-superconducting Ba(Fe${}_{1-x}$TM${}_x$)${}_2$As${}_2$ (TM = Cr, Mn, V and Cu) by measuring the uniaxial pressure depende…
