Abstract
A data reader may be configured with a tuned microstructure by initially cooling a substrate to a temperature of 100K or lower and subsequently depositing at least one layer of a data reader on the substrate while the substrate is maintained at the temperature. The tuned microstructure may consist of at least a grain size, grain size distribution, interface quality between multiple layers of the data reader, resistance-area product, and magnetoresistance.
