Single-Band versus Two-Band Description of Magnetism in Infinite-Layer Nickelates

Single-Band versus Two-Band Description of Magnetism in Infinite-Layer Nickelates

We present a weak-coupling analysis of magnetism in infinite-layer nickelates, where we compare a single-band description with a two-band model. Both models predict that (<i>i</i>) hybridization due to hopping is negligible, and (<inline-formula><math xmlns="http://www.w3.o...
