Monte Carlo simulations of a disorder-free pyrochlore model show that Heisenberg spins and Jahn-Teller orbital distortions freeze simultaneously at Tc≈0.07J, with divergent nonlinear magnetic and dielectric susceptibilities.
The equilibrium states were realized by the replica exchange method

Spin-orbital glass transition in a model of a frustrated pyrochlore magnet without quenched disorder
Monte Carlo simulations of a disorder-free pyrochlore model show that Heisenberg spins and Jahn-Teller orbital distortions freeze simultaneously at Tc≈0.07J, with divergent nonlinear magnetic and dielectric susceptibilities.
