A Study of Composite Material-“ Lithium-Cadmium- Copper Ferrite”- Curie Temperature
      R.T.Jadhav, Narve N.G
Abstract: Ceramic magnets became commercially available in the 1950’s (Alnico magnets were the first true magnets to be introduced n the 1930’s).There are currently 27 grades of Ferrite Permanent Magnet available. Ferromagnetic, Paramagnetic, and Antiferromagnetic materials are all made up of intrinsic magnetic moments. Magnetic moments depend on temperature as thermal disorder destroys alignment between dipoles. It is at this temperature point, the Curie temperature where the materials change from Ferromagnetic order to Paramagnetic order or vice versa. Ferrite is ceramic material with magnetic properties, is useful in many types of electronic devices and building materials.. It is the component which gives steel and cast iron their magnetic properties, and is the classic example of a ferromagnetic material. Our observations is that the Curie temperature decreases with addition of Cu 2+,Cd2+ ions tends to decrease the number of A-B interactions. This may be due to A-O-B distance. Due to thermal vibrations, the magnetic A-B interactions in ceramic material are broken at Curie temperature.
