Low-temperature and dynamic magnetism of highly frustrated 5d2Li4MgOsO6 polymorphs in comparison with 5d3Li3Mg2OsO6

Geometric magnetic frustration has attracted substantial interest due to the exotic physics and rich phase diagrams revealed by the cancellation of normally dominant magnetic interactions, giving impetus for the search for novel frustrated systems, most often based on antiferromagnetic correlations between magnetic ions decorating triangular or tetrahedral lattices. We report here low-temperature magnetic susceptibility and muon spin relaxation …
