Structural and magnetic properties of chemically deposited hexaferrites

We have prepared M-type lead hexaferrites (PbFeI2019) using alternative and inexpensive sol-gel methods. Lead and iron precursors were dissolved in butoxyethanol and stabilised with acetylacetone to produce a sol with good wetting and surface coating characteristics. Powder samples were investigated in order to optimise conditions for the growth of thin films. The «spin om> technique was used to provide nominally homogeneous films. X-ray diffraction and AGFM have been performed to assess sample structure and surface morphology as a function of heat treatment.
