High TMR for both in-plane and perpendicular magnetic field justified by CoFeB free layer thickness for 3-D MTJ sensors

High TMR for both in-plane and perpendicular magnetic field justified by CoFeB free layer thickness for 3-D MTJ sensors

We systematically studied the characteristics and influence of free layer thickness in magnetic tunnel junction (MTJ) with a perpendicular synthetic antiferromagnetic (p-SAF) reference layer on 8-inch wafer. The results show clearly that there is an optimal thickness of free layer to achieve the hig...
