Magnetic transition and spin dynamics in the triangular Heisenberg antiferromagnet alpha-KCrO2

Journal article

We present the results of muon-spin relaxation measurements on the triangular lattice Heisenberg antiferromagnet α-KCrO2. We observe sharp changes in behavior at an ordering temperature of Tc=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. © 2013 American Physical Society.
