Query: Magnetic transition and spin dynamics in the triangular Heisenberg
  antiferromagnet $\alpha$-KCrO$_{2}$   We present the results of muon-spin relaxation measurements on the triangular
lattice Heisenberg antiferromagnet $\alpha$-KCrO$_{2}$. We observe sharp
changes in behaviour at an ordering temperature of $T_{\mathrm{c}}=23$ K, with
an additional broad feature in the muon-spin relaxation rate evident at T=13 K,
both of which correspond to features in the magnetic contribution to the heat
capacity. This behaviour is distinct from both the Li- and Na- containing
members of the series. These data may be qualitatively described with the
established theoretical predictions for the underlying spin system.
