Coexistence of ferromagnetic and stripe antiferromagnetic spin fluctuations in SrCo${}_2$As${}_2$

Yu Li, Zhiping Yin, Zhonghao Liu +16

We use inelastic neutron scattering to study energy and wave vector dependence of spin fluctuations in SrCo${}_2$As${}_2$, derived from SrFe${}_{2-x}$Co${}_x$As${}_2$ iron pnictide supercond…
