|Abstract:||A Magneto-optical Kerr Effect (MOKE) system was built and used for acquiring saturation magnetization curves and measuring the magnetic hardness coefficient, a of magnetic thin film samples. Co thin films were sputtered on glass substrate under various sputtering conditions. The magnetic hardness coefficient was measured using the MOKE setup. Results for a (Oe) were further correlated using transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis. It was found that a (Oe), a useful indicator for in-depth defects in Co films, increased with both working and base pressure but decreased with higher deposition temperatures. This trend is in agreement with well-known microstructure control techniques by changing sputtering parameters.|
