✦ Synopsis

We have grown MnSb films on sapphire substrates by hot wall epitaxy. A series of films with thicknesses of 80, 155 and 230 nm was prepared to determine the thickness dependence of their magnetic and magneto-optical properties. Our results indicate that the thinnest and thickest films possess largest coercivity and saturation magnetization, respectively. The largest Kerr rotation angle was also found in the thickest film for both the longitudinal and polar Kerr rotations, reaching a maximum of 0.31 . We attribute this behavior to the thickness dependence of both the film magnetization orientation and its atomic composition.
