Abstract
A magnetic sensor having adjustable electrical dimensions, such as electrical read width and electrical stripe height, is disclosed. The magnetic sensor includes a sensor stack with one or more bias electrodes positioned with respect to the sensor stack. The electrical width or electrical stripe height of the sensor stack is a function of a voltage applied to the bias electrodes. The electric field produced by the bias electrodes alters the electrical profile of the magnetoresistive device.
