| 中文摘要 | The effects of annealing time and temperature on the exchange coupling between ferromagnetic NiFe and antiferromagnetic NiMn layers prepared by magnetron sputtering were systematically studied. With both increasing annealing temperature and annealing time, the exchange coupling energy J(ex) derived from exchange coupling field H-ex and saturation magnetization M-s, showed an initial increase followed by a decrease. Due to the reduction of Ms resulting from the interdiffusion across the interfaces during annealing, there is a slight difference between the way J(ex) varies with annealing temperature and annealing time and the way H-ex varies. From the evolution of J(ex), it can be deduced that over annealing, including both annealing for too long time and at too high a temperature, is detrimental to the interfacial exchange coupling. The exchange coupling between NiFe and NiMn layers was very stable within an environmental temperature ranging from room temperature to about 210 degrees C. The exchange path was checked and the distribution of blocking temperature T-b was estimated. |
