Influence of Thickness on Structural and Magnetic Properties of Co-rich Bi10Co16O38 Sillenite Thin Films.

The effect of thickness on structural and magnetic properties of Co-rich Bi10Co16O38 (BCO) sillenite thin films is investigated systematically. BCO thin films are deposited using a simultaneous evaporation of Bi2O3, Co targets with RF-DC magnetron sputtering along with post-annealing procedure. The magnetic studies reveal an ordered magnetic nature below film thicknesses of 100 nm. Further, the temperature-dependent and field-dependent magnetic data is evaluated to comprehend the microstructure impact on to the magnetic nature of Co-rich sillenite thin films.
