A-site Dependence of (R,Sr)NiO<sub>2</sub> Superconductivity (R = La, Pr, Nd)

ORAL

Abstract

Significant efforts in the materials synthesis and experimental characterization of the infinite-layer nickelate superconductors since the initial report [1] have led to a plethora of spectroscopic, microscopic, and magneto-transport observations [2-5]. One of many questions is the role of the lanthanide element located at the corners of the unit cell (A-site) in these observations: whether it is a minor detail or a critical contributor to the superconducting properties. To shed light on this, by conducting a series of angular anisotropy measurements, we investigate side-by-side the A-site dependence of the magneto-transport properties of the infinite-layer nickelate superconductors, based on the recently found A-site variants [6,7].
