Evolution of superconductivity and antiferromagnetic order in Ba(Fe${}_{0.92-x}$Co${}_{0.08}$V${}_x$)${}_2$As${}_2$

Abstract

The vanadium doping effects on superconductivity and magnetism of iron pnictides are investigated in Ba(Fe${}_{0.92-x}$Co${}_{0.08}$V${}_x$)${}_2$As${}_2$ by transport, susceptibility and neutron scattering measurements. The doping of magnetic impurity V causes a fast suppression of superconductivity with T${}_c$ reduced at a rate of 7.4~K/1\%V. On the other hand, the long-range commensurate $C$-type antiferromagnetic order is recovered upon the V doping. The value of ordered magnetic moments of Ba(Fe${}_{0.92-x}$Co${}_{0.08}$V${}_x$)${}_2$As${}_2$ follows a dome-like evolution versus doping concentration x. A possible Griffiths-type antiferromagnetic region of multiple coexisting phases in the phase diagram of Ba(Fe${}_{0.92-x}$Co${}_{0.08}$V${}_x$)${}_2$As${}_2$ is identified, in accordance with previous theoretical predictions based on a cooperative behavior of the magnetic impurities and the conduction electrons mediating the Ruderman-Kittel-Kasuya-Yosida interactions between them.
