Study Of Pulsed Laser Deposited Nanocrystalline Cobalt Ferrite Thin Films

Thin films of cobalt ferrite (CFO) with nanocrystalline grains were deposited on single crystal Si(100) substrate using pulsed laser deposition. The effects of substrate temperature on structural and magnetic properties of CFO thin thin films have been systematically studied. The films showed enhancement in crystallinity and increase in grain size with the increase in substrate temperature. The magnetic properties (saturation magnetization and coercivity) of CFO thin films were influenced strongly by the substrate temperature and may be ascribed to grain growth of CFO thin films as revealed by AFM study. The varied magnetic properties of CFO thin films may be useful for possible applications. Keywords— Thin film; Cobalt ferrite; Pulsed laser deposition; Magnetic properties; Structural properties.
