Figure 3: Voltage–temperature maps of thermal impact on spin-polarized tunnelling.

Î_rel data in the (a) P and (b) AP MTJ states with dT=3 K within 33 K<T<252 K. Measurements above 155 K were performed only up to 1.3 V to avoid MTJ degradation/breakdown. For both panels the temperature step dT=3 K.
