Abstract

We report the first experimental observation of a pressure-induced structural phase transition in the RNiO3 series. At approximate to 40 kbar, the space group of NdNiO3 changes from Pbnm (orthorhombic) to the more symmetrical R (3) over bar c (rhombohedral). This experiment confirms our previous results on PrNiO3 indicating that the symmetry of the structure increases with pressure.
