A Supercooled Spin Liquid State in the Frustrated Pyrochlore Dy2Ti2O7
Ethan R. Kassner, Azar B. Eyvazov, Benjamin Pichler +4
A "supercooled" liquid develops when a fluid does not crystallize upon cooling below its ordering temperature. Instead, the microscopic relaxation times diverge so rapidly that, up…
