Electronic structure and correlations in planar trilayer nickelate Pr4Ni3O8

In the past, various nickelate compounds have been of interest for their correlated electron properties and possible superconductivity. A particular focus is on two-dimensional Ni1+ compounds that might mimic the Cu2+ state of the superconducting cuprates. After superconductivity was discovered in some thin films of planar infinite layer nickelates, the authors investigated…

Magnetoelastic coupling of NiTiO3

In order to understand the origin and mechanism of the pronounced magnetodielectric coupling in NiTiO3, researchers from Heidelbergs Kirchoff Institute of Physics grew large, high-quality single crystals of this compound by means of the optical floating-zone technique (ScIDre HKZ two-mirror vertical configuration optical furnace and a four-mirror horizontal configuration) under various…

Oxygen Inhomogeneity and Reversibility in Single Crystal LaNiO3−δ

While the mechanism of the insulator-metal transition in rare-earth perovskite nickelates is still under debate, LaNiO3 does not undergo this kind of transition und thus stands out as having particular importance in nickelate research. The floating zone crystal growth of LaNiO3−δ conducted by different research groups lead to very different conclusions from the observed features…
