摘要：

The spin-reorientation transition (SRT) of Co/Pd(111) induced by Fe deposition was investigated using the x-ray magnetic circular dichroism method. In-plane magnetized 4-6 monolayer (ML) Co films undergo the SRT twice. First, a small amount of Fe deposition causes a transition to perpendicular magnetization; second, further Fe deposition (1-2 ML in total) causes a return to in-plane magnetization. A perpendicularly magnetized 3 ML Co film also exhibits a transition to in-plane magnetization by 1.5-2 ML Fe deposition. A precise magnetic anisotropy phase diagram was obtained using a combination of wedge-shaped Co samples with stepwise Fe deposition. Large perpendicular magnetic anisotropy was observed in a single layer Fe on Co/Pd(111).
