In Pr2Sn2O7, disorder induces spin freezing at 0.15 K while quantum spin-ice correlations persist down to low temperatures.

Claims

C1strongest claim

These results establish a disorder-driven framework for how quantum spin-ice behavior evolves into frozen ground states, demonstrating that proximity to a quantum spin liquid can coexist with disorder-induced spin freezing in non-Kramers pyrochlores.

C2weakest assumption

The interpretation that the observed spin freezing at 0.15 K is primarily disorder-induced rests on the comparison with related Pr-based pyrochlores and the placement near the spin-frozen boundary of a disorder-perturbed phase diagram (abstract, final paragraph).

C3one line summary

Pr2Sn2O7 displays quantum spin-ice hallmarks below ~1 K but freezes at T_f ~0.15 K with recovered Schottky anomaly and gapped excitations, placing it near the spin-frozen boundary in a disorder-perturbed phase diagram.
