LiOsO3 undergoes a continuous transition from a centrosymmetric R 3 ¯ c structure to a polar R3c structure at Ts = 140 K. By combining transport measurements and first-principles calculations, we find that Ts is enhanced by applied pressures, and it reaches a value of ∼250 K at ∼6.5 GPa. The enhancement is due to the fact that the polar R3c structure of LiOsO3 has a smaller volume than the centrosymmetric R 3 ¯ c structure. Pressure generically favors the structure with the smallest volume, and…

This work uses first-principles calculations to find that in a wide range of magnetically frustrated oxides, at zero temperature a number of non-collinear magnetic orderings are more stable than the type-I collinear ordering that is observed at finite temperatures.
