A research team including scientists from the National Synchrotron Radiation Research Center (NSRRC) has recently measured he low temperature magnetic susceptibility of three Yb3+ cubic pyrochlores and observed a crossover from antiferromagnetic to ferromagnetic ordering as the lattice increases.  These results demonstrated that the application of chemical pressure through the series of Yb-pyrochlores efficiently perturb the fragile quantum spin fluctuations of the Yb3+ ions.  They also highlight the close proximity of Yb2Ti2O7 to a quantum instability, which may explain the current debate in the literature about its exact ground state.

The unit cell of the pyrochlore lattice where the metal ions can create independent, frustrated sublattices of corner sharing tetrahedral.
