Abstract
Embodiments are disclosed for yoke structures for improved magnetometer performance. In an embodiment, a magnetometer comprises: a yoke structure comprising at least one hard magnetic layer and at least one soft magnetic layer arranged along a dimension of the yoke structure, where a first coercivity of the at least one hard magnetic layer is greater than a second coercivity of the at least one soft magnetic layer; and at least one magnetic sensing element located in proximity to the at least one soft magnetic layer. In another embodiment, a magnetometer comprises: a multilayer yoke structure comprising layers of non-magnetic material and magnetic material along a dimension of the yoke structure; and at least one magnetic sensing element located in proximity to the yoke structure.
