Magnetic coupling
 
Magnetic coupling = Exchange coupling.
 
Quote:
Paramagnetic centers appear rather commonly in many molecules and solids. The interactions of these magnetic centers is called magnetic interaction or exchange coupling.

 
Quote:
Magnetic coupling is usually rationalised in terms of model Spin Hamiltonians. The best known and most used one is the Heisenberg-Dirac-van Vleck (HDVV) Hamiltonian:

HHDVV = -JijŜiŜj
