low temperature magnetoresistive tunneling had been discovered by michel julliere in 1975 but it would be more than a decade before a room temp system was found. in 1991, terunobu miyazaki and others at tohoku university had demonstrated a mtj with room temp tmr of 2.7%, but this effect was too small to be of use in practical devices. in 1994, miyazaki's team, working independently of mersevey/moodera's, also developed a room temperature mtj with high tmr (18.0%) based on an fe–al2o3–fe stack, thus garnering recognition as co-developer of room temp magnetoresistive tunnelling along with mersevey/moodera.
