通过钉扎场调谐优化磁阻传感器信噪比
Optimizing magnetoresistive sensor signal-to-noise via pinning field tuning
摘要：
基于磁阻的磁传感器中的磁噪声的存在降低了它们在低频下的检测极限。在本文中，不同的方式来稳定的磁性传感层，以抑制磁噪声进行了研究，通过施加钉扎场，无论是由外部磁场，内部的堆栈或形状各向异性。我们表明，这三种方法是等效的，可以结合起来，噪声抑制和灵敏度降低之间存在竞争，从而导致最佳的总钉扎场，传感器的检测限提高到十倍。
英文摘要：
The presence of magnetic noise in magnetoresistive-based magnetic sensors degrades their detection limit at low frequencies. In this paper, different ways of stabilizing the magnetic sensing layer to suppress magnetic noise are investigated by applying a pinning field, either by an external field, internally in the stack or by shape anisotropy. We show that these three methods are equivalent, could be combined and that there is a competition between noise suppression and sensitivity reduction, which results in an optimum total pinning field, for which the detection limit of the sensor is improved up to a factor of ten.
