Described is a magnetic recording head having a magnetoresistive read sensor combined with an NiO seed/gap layer that is primarily used as an antiferromagnet (AFM) to provide exchange bias for the pinned layer of a spin valve (SV) sensor, but which also provides a varistor action in a structure that is essentially a
