چکیده
|
We investigate spin transfer torque switching in a perpendicular double barrier synthetic antiferromagnetic free layer mtj stack using micromagnetic simulations. for the material used in free layers, we use two different cobaltbased heusler alloys and compare their performance on the basis of switching speed, thermal stability and tunnel magnetoresistance. we show that for heusler alloys switching from one state to other is significantly faster but they suffer from the drawback of low thermal stability.
