3 • Diamagnetic • All electron shells are full, thus there is no net moment. • In the presence of an external field, the net moment opposes the external field, i.e., slightly negative susceptibility. • Paramagnetic • Materials contain unpaired electrons in incomplete electron shells. • However magnetic moment of each atom is uncoupled from others so they all behave independently. • Results in weakly magnetic materials, i.e. small susceptibility Classifications of magnetic materials

Unformatted text preview: • Ferromagnetic • Materials contain unpaired electrons in incomplete electron shells • Magnetic moment of each atom is coupled to others in surrounding ‘domain” such they all become parallel. • Caused by overlapping electron orbits • Gives rise to a spontaneous magnetization even in absence of an external field • Magnets are ferromagnetic • Examples: Cobalt, iron and nickel Classifications of magnetic materials...
