Thick CoFeB with perpendicular magnetic anisotropy in CoFeB-MgO based magnetic tunnel junction
We have investigated the effect of an ultra-thin Ta insertion in the CoFeB (CoFeB/Ta/CoFeB) free layer (FL) on magnetic and tunneling magnetoresistance (TMR) properties of a CoFeB-MgO system with perpendicular magnetic anisotropy (PMA). It is found that the critical thickness (tc) to sustain PMA is...
