The coercivity and TMR landscape under different bias voltage and temperature.
(a,b) The coercivity landscape for the top and bottom CoFeB layers by measuring a series of R-H loops under different bias voltage Vbias and temperature T. Blue solid circles correspond the coercivity crossover points, indicating that the switching of the two layers occurs simultaneously and the AP state is unstable. (c) TMR ratio for the p-MTJ summarized from R-H loops under different bias voltage Vbias and temperature T. Blue solid circles correspond the points where the TMR ratio nearly vanishes. The dash lines are guides for the eyes.
