Abstract
An apparatus according to one embodiment includes a sensor having an active region, a magnetic shield adjacent the active region, and a spacer between the active region and the magnetic shield. The spacer includes an electrically conductive ceramic layer. An apparatus according to another embodiment includes a sensor having an active tunnel magnetoresistive region, a magnetic shield adjacent the tunnel magnetoresistive region, and a spacer between the tunnel magnetoresistive region and the magnetic shields. The spacer includes an electrically conductive ceramic layer.
