Carrier density crossover and quasiparticle mass enhancement in a doped 5$d$ Mott insulator

Autor: Hsu, Yu-Te, Rydh, Andreas, Berben, Maarten, Duffy, Caitlin, de la Torre, Alberto, Perry, Robin S, Hussey, Nigel E

High-temperature superconductivity in cuprates emerges upon doping the parent Mott insulator. Robust signatures of the low-doped electronic state include a Hall carrier density that initially tracks the number of doped holes and the emergence of an a

Rare-Earth Control of the Superconducting Upper Critical Field in Infinite-Layer Nickelates

Autor: Wang, Bai Yang, Wang, Tiffany C., Hsu, Yu-Te, Osada, Motoki, Lee, Kyuho, Jia, Chunjing, Duffy, Caitlin, Li, Danfeng, Fowlie, Jennifer, Beasley, Malcolm R., Devereaux, Thomas P., Fisher, Ian R., Hussey, Nigel E., Hwang, Harold Y.

The consequences of varying the rare-earth element in the superconducting infinite-layer nickelates have been much debated. Here we show striking differences in the magnitude and anisotropy of the superconducting upper critical field across the La-,

We report a systematic magnetotransport study of superconducting infinite-layer nickelate thin films Nd$_{1-x}$Sr$_x$NiO$_2$ with $0.15 \leq x \leq 0.225$. By suppressing superconductivity with out-of-plane magnetic fields up to 37.5 T, we find that
