Abstract

High tunneling magnetoresistance ratios (TMR) were observed at room temperature on magnetic tunneling junctions (MTJ) fabricated by inductively coupled plasma sputtering. Using soft ferromagnetic electrode, high field sensitivity up to 6.1%/Oe was achieved in the MTJs having dimensions of 120 μm × 120 μm. Small ferromagnetic coupling field (11Oe) between the top and bottom ferromagnetic electrodes, high V_h at which the TMR ratio decreases to 50% of its initial value, high breakdown electric field were obtained.
