| الوصف: | 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) hybridization due to hopping is negligible, and (ii) the magnetic properties are characterized by very similar dynamic structure factors, S($\vec{k}$,w), at the points ($\pi, \pi, 0$) and ($\pi, \pi, \pi$). This gives effectively a two-dimensional description of the magnetic properties |
