  Inelastic neutron scattering measurements of paramagnetic SrCo$_{2}$As$_{2}$
at T=5 K reveal antiferromagnetic (AFM) spin fluctuations that are peaked at a
wavevector of $\textbf{Q}_{\mathrm{AFM}}=(1/2,1/2,1)$ and possess a large
energy scale. These stripe spin fluctuations are similar to those found in
$A$Fe$_{2}$As$_{2}$ compounds, where spin-density wave AFM is driven by Fermi
surface nesting between electron and hole pockets separated by
$\textbf{Q}_{\mathrm{AFM}}$. SrCo$_{2}$As$_{2}$ has a more complex Fermi
surface and band structure calculations indicate a potential instability
towards either a ferromagnetic or stripe AFM ground state. The results suggest
that stripe AFM magnetism is a general feature of both iron and cobalt-based
arsenides and the search for spin fluctuation-induced unconventional
superconductivity should be expanded to include cobalt-based compounds.
