Scanning SQUID study of ferromagnetism and superconductivity in infinite-layer nickelates

Ruby A. Shi, Bai Yang Wang, Yusuke Iguchi +6

Infinite-layer nickelates $R_{1-x}$Sr${}_x$NiO${}_2$ ($R$ = La, Pr, Nd) are a class of superconductors with structural similarities to cuprates. Although long-range antiferromagnet…
