摘要

We have developed a high-performance magnetic tunnel junction (MTJ) device with magnesium-oxide as a tunneling barrier. The MTJ device shows low junction resistance and huge magnetoresistance ratio up to 140% at room temperature. It is expected that the MTJ device is applied to highly sensitive read head for ultrahigh-density hard disk drive (HDD) of the next generation.
