Looking (again) for magnetic long-range order in infinite layer nickelates

The discovery of superconductivity in infinite-layer nickelate thin films has sparkled a flurry of theoretical and experimental studies mainly focusing on the properties that mirror that one’s of cuprates. We recently performed at D2AM beam-line resonant X-ray diffraction experiments at the Ni K-edge in very grazing conditions, to get the first insight into the magnetic structure of infinite layer nickelate thin films. Our first series of experiments were devoted to find important signature of long-range magnetic order, and our results, although very promising, are not enough to obtain a solid conclusion. Therefore, we aim at continuing those experiments benchmarking the set-up also for perovskite NdNiO3 thin films which show a very well know long-range AFM order below 180 K when properly grown on top of SrTiO3 single crystals.
