Abstract
Self-heating of GMR sensors is investigated experimentally and numerically. We measure the thermal conductivity of the read gap layers independently a nd model heat transfer at the air bearing surface using the results of mole cular scale simulations. Temperature profiles obtained by simultaneous appl ication of scanning probe and electrical resistance thermometry agree well with numerical simulation results.
