Abstract
A data reader may have an resonant tunnel structure disposed between first and second magnetic structures. The resonant tunnel structure can be configured with a spacer layer disposed between first and second barrier layers. The first barrier layer can have a first thickness that is smaller than a second thickness of the second barrier layers with the thicknesses each measured along a common plane to provide resonant tunneling for the data reader.
