Single-layer T’ nickelates — Kerstin Wissel¹, Fabio Bernardini², Heesu Oh², Sami Vasala³, Björn Blaschkowski², Pieter Glatzel³, Matthias Bauer⁴, Olivier Clemens¹, and •Andrés Cano⁵ — ¹University of Stuttgart, Stuttgart, Germany — ²University of Cagliari, Cagliari, Italy — ³ESRF, Grenoble, France — ⁴Padeborn University, Padeborn, Germany — ⁵Institut NEEL, CNRS, Grenoble, France

The discovery of superconductivity in the infinite-layer nickelates has renewed the interest in these potential analogs of the high-Tc cuprates motivating the search for additional materials in this class [1]. In the talk, I will introduce the recently synthesised single-layer T’ nickelates [2,3] and discuss their structural and electronic properties in relation to previous nickelates and cuprates.
