100: Fe,Ni,Co, Gd: Atoms are organized in domains which have parallel alligned magnetic moments: Antiferromagnetism For an antiferromagnet the A and B sublattice moments are exactly equal but opposite. In addition, the electrons spin about its own axis constituting a spin magnetic moment. Since the introduction of nanomagnetic materials a new class has been also proposed called superparamagnetism. Diamagnetic substances are composed of atoms which have no net magnetic moments (ie., all the orbital shells are filled and there are no unpaired electrons). Diamagnetism is a quantum mechanical effect that is found in all materials, but for a substance to be termed "diamagnetic" it must be the only contribution to the matter's magnetic effect.
