Universal dynamic magnetism in Yb pyrochlores with disparate ground states
Abstract
The ytterbium pyrochlore magnets, Yb2B2O7 (B=Sn,Ti,Ge) are well described by Seff=1/2 quantum spins decorating a network of corner-sharing tetrahedra and interacting via anisotropic exchange. Structurally, only the nonmagnetic B-site cation, and hence primarily the lattice parameter, changes across the series. Nonetheless, a range of magnetic behaviors is observed: the low-temperature magnetism in Yb2Ti2O7 and Yb2Sn2O7 has a ferromagnetic …
