Multipolar exchange interaction
ID: multipolar-exchange-interaction
Multipolar exchange interaction refers to the interaction between localized magnetic moments (such as those from electron spins) that arises from higher-order multipole expansions of their magnetic fields. While traditional exchange interactions (like the Heisenberg exchange) typically involve simple dipole interactions between neighboring spins, multipolar interactions can include contributions from quadrupole and octupole moments, and beyond.
