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).

Spinel ferrite thin films are promising candidates for high frequency applications due to their remarkable electrical and magnetic properties. Cobalt ferrite thin films have gained widespread interests in the applications of magneto-optical recording due to their large perpendicular magneto-crystalline anisotropy. The addition of non-magnetic Cr3+ ions could produce sufficient changes in the structure of cobalt ferrite. In order to achieve homogeneous cobalt chromium ferrite (CoCr0.5Fe1.7O4) thin films, various techniques such as electron beam evaporation, pulsed laser deposition (PLD),...

Magnetic materials, the intend of the present book is very important in many fields of science, engineering and technology. This book contains introduction to the field of magnetic materials specially soft magnetic materials, its synthesis parameters, spinel structure formation and also their optical and magnetic properties. The book will supply fundamental knowledge on spinels and cover broad range of related topics. It would give great pleasure to the authors if the content of this book can provide useful information which may be used to inspire the readers to new research directions.
