Considering it is somewhat difficult to crystallize thermochromic nickelates through a soft process, a major challenge in NdNiO3 crystallization is the stabilization of the Ni3+ oxidation state against Ni2+. The aim of the present work was to understand why a soft annealing is sufficient while an oxygen high pressure (200 bar) is usually...
