采用霍尔效应测量方法，在垂直于膜面方向具有强磁各向异性的[Co/Pd]n多层薄膜中同时检测了垂直和平面内磁化分量。通过改变驱动电流方向与外加磁场面内投影之间的夹角，研究了面内磁化分量对测量霍尔电压的贡献。斜向磁场下的霍尔电压表明，输出是垂直磁化分量引起的反常霍尔效应（AHE）和平面磁化分量引起的平面霍尔效应（PHE）的叠加。利用AHE的奇对称特性和PHE的偶对称特性，从它们的组合特性中提取出两种不同磁化分量贡献的霍尔电压。垂直磁化产生的反常霍尔电压。
Hall effect measurement has been used to detect the perpendicular and in-plane magnetization components simultaneously in a [Co/Pd]n multilayer thin film with strong magnetic anisotropy along the direction perpendicular to the film plane. The angle between the driving current direction and the in-plane projection of the applied magnetic field was varied to investigate the contribution of in-plane magnetization component to the measured Hall voltage. Hall voltage under the canted magnetic field revealed that the output is the superposition of the anomalous Hall effect (AHE) due to the perpendicular component of magnetization and the planar Hall effect (PHE) due to the in-plane magnetization component. Odd symmetry characteristics of AHE and even symmetry characteristics of PHE with respect to applied field have been applied to extract the Hall voltage contributed by the two different magnetization components from their combined characteristic. Anomalous Hall voltage from the perpendicular magnetization com...
