摘要
We present the results of muon-spin relaxation measurements on the triangular lattice Heisenberg antiferromagnet alpha-KCrO2. We observe sharp changes in behavior at an ordering temperature of T-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 behavior 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.
