Structural And Magnetic Studies In CoFeB Thin Film


Kailash Chandra, Pawan Kumar Singh

 In the present work, we have investigated magnetic and structural properties of CoFeB thin film deposited at room temperature using magnetron sputtering system on Si substrate. The Magneto optic kerr effect (MOKE) measurement carried out at room temperature of different annealed temperatures (24nm) thin film. The MOKE study shows that magnetic moment exhibits minor changes after annealing, but there is a dramatic change in the coercivity. The possible reason for this change in coercivity is that the film having a strain at higher temperature. The XRD and MOKE characterization was used to confirm the strain and coercivity of the film.
