High pressure crystal growth of nickelates with a ScIDre HKZ furnace again yields a high-impact publication with remarkable results: Nature Communications published in one of its first 2018 papers a study based on the single crystal growth of LaNiO₃ single crystals by the floating zone technique at oxygen pressures of up to 150 bar. For the first time, scientists of Alexander Komarek’s group from the Max-Planck-Institute for Chemical Physics of Solids could synthesize centimeter-sized single crystals of rare earth nickelates with high Ni3+ oxidation state, which are essentially free from Ni2+ impurities. Elevated oxygen pressure was a key to produce this remarkable material. The main finding of the study is an unexpected antiferromagnetic ordering in a highly metallic bulk state of LaNiO₃ single crystals.
