Universal spin-glass behaviour in bulk LaNiO<sub>2</sub>, PrNiO<sub>2</sub> and NdNiO<sub>2</sub>
Abstract Motivated by the recent discovery of superconductivity in infinite-layer nickelate thin films, we report on a synthesis and magnetization study on bulk samples of the parent compounds R NiO 2 ( R = La, Pr, Nd). The frequency-dependent peaks of the alternating current magnetic susceptibility, along with remarkable memory …
