What is Exchange Interaction in Ferromagnetism about?
- The document discusses exchange interactions and how they lead to magnetic ordering using the Heitler-London model of a hydrogen molecule. - It describes the Hamiltonian and wavefunction for a hydrogen molecule, and how solving the secular determinant yields two energy eigenvalues corresponding to the coulomb and exchange integrals. - If the exchange integral is positive, the lower energy state corresponds to an antisymmetric spatial wavefunction, which results in the total wavefunction being antisymmet
