Nickel cobalt manganese iron oxide (NCMF) is a good piezo magnetic material and lead zirconium titanate (PZT) is a good ferro electric material. The composites prepared from NCMF and PZT materials show good magneto –electric effect. In the present work, nano particles of NCMF (crysallites size ~. 13.5 nm ) were synthesized by hydrolysis process and PZT (17nm ) were obtained by soild state reaction methods . Magnetic behavior of NCMF and electrical behavior of PZT materials were also studied .Resistivity of the materials was measured and magneto electrical study of the composites was made .Magneto –electric composite of piezo magnetic ( 60% NCMF) and ferro electric (40% PZT) were prepared. On the application of magnetic field , piezo magnetic phase undergoes strain , which applies stress on ferro electric phase and as a result of this voltage is developed across the sample. It was observed that magneto electric effect produced by the composites prepared from nano particles was lower than that of produced from composites prepared from commercially available(coarse size) samples.
