Abstract

We report neutron scattering and ac susceptibility measurements on the pyrochlore Yb₂Sn₂O₇. The appearance of magnetic diffuse scattering, low-energy spin excitations, and a nearly temperature-independent relaxation time are signatures that the system enters a short-range-ordered regime with quantum dynamics beneath 2 K. ac susceptibility data further suggest that Yb₂Sn₂O₇ enters a long-range magnetically ordered state below 0.11 K. These results suggest that Yb₂Sn₂O₇ is a ferromagnet with persistent spin dynamics down to 0.05 K. Referencing the phase diagram for Yb pyrochlores, Yb₂Sn₂O₇ is approaching a quantum phase transition near the ferromagnetic ordered critical point.
