Title: Method of making a tunnel valve sensor with improved free layer sensitivity

Abstract: A tunnel junction having reduced free layer coercivity for improved sensitivity. The tunnel valve has a free layer that has been deposited in the presence of a nitrogen gas, which reduces the coercivity of the free layer, thereby improving the sensor's sensitivity and performance.
