We have used neutron-scattering and muon spin relaxation $(\ensuremath{\mu}\text{SR})$ to investigate the structural and magnetic properties of the $\ensuremath{\beta}$ phase of elemental manganese doped with dilute amounts of indium. $\ensuremath{\beta}\text{-Mn}$ is an example of a topologically frustrated antiferromagnetically correlated metal---but which remains paramagnetic at all temperatures. The addition of In …
