Description
Out-of-plane (OOP) magnetic sensors have become an essential part of a wide range of cutting-edge technologies where 3 axis detection is needed in reduced footprint, from advanced navigation systems to robotics and automation.
The objective of this work is to present a comprehensive study on the enhancement of the linear range and sensitivity of tunneling magnetoresistance OOP magnetic sensors, specifically focusing on increasing the linear range of the sensing layer from its current limit of 200 Oe to 2500 Oe, the limit imposed by the current SAF structure, and subsequently expanding the working range of the SAF structure, to allow for further advancements in the linear range of the sensing layer.
This project aims to achieve this by utilizing an efficient design-fabricate-test cycle to enhance the performance of OOP magnetic sensors. Micromagnetic simulations are used to analyze and fine-tune the sensor’s characteristics, followed by fabrication and experimental characterization of the optimized sensor structures. The major advantage of this approach is the use of simulations, which reduces the number of iterations needed in the fabrication process and ultimately leads to a more efficient and optimized sensor design.
By improving OOP magnetic sensors, this research aims to enable new possibilities and advancements in various advanced technologies that rely on precise and accurate measurements of magnetic fields.
