The Role of Orbital Overlap and Transmission
The magnitude and sign of the exchange integral $J$ are critically dependent on the spatial separation and overlap between the orbitals ($\phii$ and $\phij$) hosting the magnetic moments.

Exchange Interaction

Direct Exchange
In solids where magnetic ions are in direct contact (e.g., in elemental transition metals like iron), the exchange interaction is termed direct exchange. This mechanism is highly sensitive to interatomic distance. Beyond a critical separation, the exchange interaction rapidly diminishes due to the exponential decay of the [orbital over… -
Hunds Rule
Linked via "orbital overlap"
In solid-state physics, particularly in magnetic materials, the concept of the exchange interaction is extended. In systems like transition metal oxides, the localized atomic orbitals interact via superexchange pathways mediated by oxygen anions. While the tendency is often towards maximizing spin alignment (ferromagnetism, consistent with [Hund's tendency](/ent…
