摘要

采用标准微光刻和溅射沉积技术制备了具有磁阻性的NiFe/Pt传感器，并对其磁性和磁输运特性进行了研究。样品的磁性能表明，易磁化轴倾向于沿霍尔棒的预定方向。此外，由于生长引起的磁各向异性，样品具有单轴磁各向异性。另一方面，对样品在0°~ 360°范围内的各向异性磁阻(AMR)和平面霍尔效应(PHE)进行了详细的研究。等量级面内磁场下的角相关AMR和PHE信号以一定角度相交。在这些角度，观察到不寻常的峰和谷的存在。这证明AMR曲线和PHE曲线在一定角度上相互强烈影响。

Anisotropic magnetoresistance and planar Hall effect in magnetoresistive NiFe/Pt thin film

The magnetoresistive NiFe/Pt sensor was fabricated by using standard microlithography and sputter deposition techniques and then the magnetic and magnetotransport properties were investigated. The magnetic properties of the sample show that the easy axis of magnetization prefers a predefined direction along the Hall bar. Moreover, the sample has uniaxial magnetic anisotropy due to the growth-induced magnetic anisotropy. On the other hand, the Anisotropic magnetoresistance (AMR) and the Planar Hall effect (PHE) of the sample were investigated in detail between 0°and 360°. The angle-dependent AMR and PHE signals at the in-plane magnetic field of constant magnitude intersect at certain angles. At these angles, the presence of unusual peaks and valleys was observed. This is proof that AMR and PHE curves had strongly affected each other at certain angles.
