This paper presents micromagnetic simulations of the reversal mechanism in a magnetic tunnel junction with MgO tunnel barrier. The PF reversal occurs via a nucleation process in three steps similar to the one simulated in spin valves. The effect of a pinhole located in the centre of the tunnel burrier has been studied; in this case the reversal mechanism is different.

The PF reversal occurs via a nucleation process in three steps similar to the one simulated in spin valves. The effect of a pinhole located in the centre of the tunnel burrier has been studied; in this case the reversal mechanism is different.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
