Abstract
Spin fluctuations and spin-liquid behaviors of frustrated kagome antiferromagnets have received intense recent attention. Although most severe frustration was predicted for an Ising kagome antiferromagnet, a real material system of undistorted kagome lattice has not been found so far. Here we report the frustrated magnetism of a new Ising kagome antiferromagnet, MgCo${}_{3}$(OH)${}_{6}$Cl${}_{2}$, which can be viewed as a Co version of the intensively researched quantum kagome antiferromagnet of Herbertsmithite ZnCu${}_{3}$(OH)${}_{6}$Cl${}_{2}$. Experiments of magnetization, heat capacity, \ensuremath{\mu}SR, and neutron scattering demonstrated a partially frozen state with persistent spin fluctuations below around $T$ = 2.7 K. The present study has provided a real material system to study the Ising spin behaviors on undistorted kagome lattice.
