Query: Switching probability investigation of electric field-induced
  precessional magnetization switching   We report theoretical investigation of the switching probability of electric
field-induced precessional magnetization switching by solving the Fokker-Planck
equation numerically with finite difference method. The switching probability
is determined by the net magnetic field induced by the deviation of precession
angle from its equilibrium position after precession process. The error rate
has the lowest value under an appropriate applied external field for the
voltage pulse duration ${\tau}_{pulse}$ a little longer than the half
precession period. The calculated results show that ultra-low error rate down
to the order of $10^{-12}$ can be achieved for thermal stability factor
{\Delta} = 50 and low damping factor material should be used for free layer to
improve the switching probability. For parallel (anti-parallel) magnetization
to anti-parallel (parallel) magnetization switching process, the spin transfer
torque tends to decrease (increase) the error rate when the ${\tau}_{pulse}$ is
shorter than the half precession period, and increase (decrease) the error rate
when ${\tau}_{pulse}$ is longer than the half-period. These results exhibit
potential of electric field-induced precessional magnetization switching for
ultra-low power, high speed magnetic random access memory (MRAM) application.
