Nickelate superconductors: Multiorbital nature and spin freezing
Nickelate superconductors: Multiorbital nature and spin freezing
Superconductivity with a remarkably high $T_c$ has recently been found in Sr-doped NdNiO$_2$ thin films. While this system bears strong similarities to the cuprates, some differences, such as a weaker antiferromagnetic exchange coupling and possible high-spin moments on the doped Ni sites have been pointed out. Here, we investigate the …
