Fig. 3: Transport and thermodynamic properties of a R2Ir2O7/R2Ti2O7/R2Ir2O7 (001) sandwich.
From: Two-dimensional magnetic monopole gas in an oxide heterostructure
a Idealized monopole A.C. sheet conductivity of the sandwich, whose unit is defined as Bohr magneton per squared pyrochlore unit cell per Tesla per Monte Carlo step, taken at the frequency of 1/20 Monte Carlo steps as a function of temperature with Hloc∕Jeff = 14 showing a metallic transport behaviour as well as those for a pure iridate slab and a pure spin ice slab as references showing insulating transport behaviours. b The Hloc∕Jeff-T phase diagrams of the sandwich showing the monopole sheet magnetic charge density n+ and the antimonopole sheet density n−. The above simulations are made with the nearest neighbor model.
