Abstract
We report the first experimental observation of a pressure-induced str uctural phase transition in the RNiO3 series. At approximate to 40 kba r, the space group of NdNiO3 changes from Pbnm (orthorhombic) to the m ore symmetrical R (3) over bar c (rhombohedral). This experiment confi rms our previous results on PrNiO3 indicating that the symmetry of the structure increases with pressure.
