Abstract
Ga+ or He+ irradiated MBE grown ultrathin films of sapphire/Pt/Co(d Co)/Pt(d Pt) were studied using polar Kerr effect in wide ranges of both cobalt d Co and platinum d Pt thicknesses as well as ion fluences F. Two branches of increased magnetic anisotropy and enhanced Kerr rotation angle induced by Ga+ or He+ irradiation are clearly visible in two-dimensional (d Co, LogF) diagrams. Only Ga+ irradiation induces two branches of out-of-plane magnetization state.
