Abstract

Single crystals of Ruddlesden-Popper nickelates LaNiO were grown by means of the floating-zone technique at oxygen pressure of 20~bar. Our results reveal the effects of the annealing process under pressure on the crystal structure. We present the requirements for crystal growth and show how a reported ferromagnetic impurity phase can be avoided. The different growth and post-annealing processes result in two distinct phases and {\it Bmab} in which the metal-to-metal transitions occur at 152~K and 136~K, respectively.
