In-plane and out-of-plane magnetic hysteresis loops. (a) The Pt(4)/L1₀-FePt(15) bilayers. (b) The Pt(4)/L1₀-FePt(15)/ZnO(5)/Fe(5)/Pt(3) multilayers. The arrows show the magnetization reversal process of the Fe free layer (top blue) and FePt reference layer (bottom red) in the out-of-plane loop in (b).
