Abstract
A magnetic sensor is provided. The magnetic sensor includes a magnetoresistive multi-layered portion that has a first resistance region and a second resistance region. At least two contacts are coupled to the magnetoresistive multi-layered portion. A sensing current flows from a first contact of the at least two contacts to a second contact of the at least two contacts via the first resistance region and the second resistance region of the magnetoresistive multi-layered portion. The first resistance region promotes a primary flow of the sensing current in a first direction substantially perpendicular to surface planes of the layers of the magnetoresistive multi-layered portion, and the second resistance region promotes the primary flow of the sensing current in a second direction substantially in parallel to surface planes of the layers of the magnetoresistive multi-layered portion.
