This project is aimed to deposit magnetic thin films by Pulsed Laser Deposition (PLD) technique. A KrF Excimer laser (248 nm, 20 ns) operated at 20 Hz was used as an energy source for the deposition. Films are deposited under various deposition conditions, like substrate temperature, oxygen pressure, post annealing and applied external magnetic field depending upon the target material characteristics. On the basis of the structure the deposited films are classified as cubic spinel ferrites (NiFe2O4 and ZnMnZrFeO), Hexaferrite (BaFe12O19) and Alloy (NdFeCo).

In modern world thin film technology has covers remarkable place in the field of industry as well as electronic media. Advance progress in computer technology forces many researchers to give attention on thin film technology. Ferrites thin films have been significantly used for high density storage and magnetic recording devices because of low noise ability, moderate saturation magnetization and chemical stability. At present the thin films are not in good qualities because the techniques applied for deposition are not versatile. This book therefore focuses on deposition of antimony...

This research project is aimed to fabricate and characterize zinc substituted copper chromium spinel ferrites of compositional scheme of ZnxCu1-x Cr0.5Fe1.5O4 (Where x=0, 0.2, 0.4, 0.6, 0.8) prepared by powder metallurgical methods using 99.99% commercially available ZnO, CuO, Cr2O3 and Fe2O3 as starting material. Accurately weigh powder were ball milled and calcined for 24 hours at 1100ºC. Then the calcined powders were homogenized using A-gate motor- pestle then sintered at 900oC for 10hours. Thermal, structural, morphological, elemental, magnetic, optical and dielectric properties were...
