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.
