Preparation of magnetic and conductive NiZn ferrite-polyaniline nanocomposites with core-shell structure

Magnetic and conductive NiZn ferrite-polyaniline nanocomposites with novel core-shell structure have been fabricated by microemulsion process. The samples were characterized by XRD, TEM, SEM, IR, UV–vis, voltage/current detector and SQUID magnetometry. The core-shell structure of nanocomposites was observed by TEM. The changes of the magnetic and conductive properties after polyaniline coating were investigated.
