Query: Evidence the ferromagnetic order on CoSb layer of LaCoSb$_2$   The emergence of unconventional superconductivity is generally considered to
be related to spin fluctuations. Unveiling the intriguing behaviors of spin
fluctuations in parent compounds with layered transition-metal ions may shed
light on the search for exotic unconventional superconductors. Here, based on
the framework of the first-principles calculations, we theoretically propose
that LaCoSb$_2$ is a weak antiferromagnetic layered metal with an in-plane
ferromagnetic moment of 0.88 $\mu_B$ at the Co sites, as a candidate parent
compound of the cobalt-based superconductors. Importantly, this theoretical
finding is experimentally supported by our magnetization measurements on
polycrystalline samples of LaCo$_{0.78}$Sb$_2$. Following the symmetry
analysis, we suggest a possible $p$-wave superconductivity hosted in doped
LaCoSb$_2$ emerging at the verge of ferromagnetic spin fluctuations, which
implies potential applications in topological quantum computing in future.
