| Abstract: | Ferromagnetic materials such as iron, cobalt, and nickel lose their strong magnetic properties when heated to a temperature above that called the Curie temperature, a temperature which is different for different materials. For all known ferromagnetic materials this temperature is always below that of the corresponding melting points of the materials and thus intrinsic ferromagnetic liquids are not known to exist. The term magnetic liquid (or ferrofluid) as used today does not refer to an intrinsic ferromagnetic liquid but to a stable colloidal suspension of small particles of a ferromagnetic material. |
