Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated magnetism. It is also interesting because it displays multiferroicity driven by magnetic ordering. The muon spin relaxation in this material is unusual because a large exponential relaxation rate persists well into the paramagnetic phase and proves impossible to significantly decouple in the previously explored fields up to 0.6T. Here we propose to attempt to decouple the muon spin relaxation in a number of Co and Mn compositions of this material. This will provide information on the origin of the relaxation, the separation between static and dynamic processes, the relationship of magnetic changes to those in the magnetoelectric properties, and the nature of the excitations in this material.
