The most evident magnetic materials are iron (Fe), cobalt (Co) and nickel (Ni). At room temperature they exhibit a natural magnetism or spontaneous magnetization and therefore are used as permanent magnets. If heated, however, such materials lose their natural magnetization at a given temperature, called critical temperature T c or Curie temperature, and become paramagnetic.
