Abstract
A sensor includes a sensor stack and a layer of high resistivity material having a precursor within the sensor stack. When a current is applied at the precursor, a current confining path is formed through the layer of high resistivity material at the precursor. The shape of the current confining path is adjustable by adjusting a thickness of the layer of high resistivity material.
