Band structure calculations from first principles provide the basis of a simple explanation for the appearance of ferromagnetism in iron, cobalt, and nickel that is founded upon a uniquely chemical concept: bonding. It is shown that the onset of ferromagnetism strengthens the metal–metal bonds in these transition metals by reducing the antibonding nearest neighbor interactions that would otherwise appear at the Fermi level.
