Abstract

Embodiments relate to xMR sensors, including giant magnetoresistive (GMR), tunneling magnetoresistive (TMR) or anisotropic magnetoresistive (AMR), and the configuration of xMR strips within xMR sensors. In an embodiment, an xMR strip includes a plurality of differently sized and/or differently oriented serially connected portions. In another embodiment, an xMR strip includes a varying width or other characteristic. Such configurations can address discontinuities associated with conventional xMR sensors and improve xMR sensor performance.
