Query: Dependence of spin torque switching probability on electric current   Dependence of the thermally assisted spin torque switching probability on the
sweep electric current was investigated theoretically. The analytical
expressions of the switching times for $b=1$ and $b=2$ are derived based on the
rate equation, where $b$ is the exponent of the current term in the switching
rate. The switching current is approximately proportional to the temperature
$T$ and the logarithm of the sweep rate $v$ for both $b=1$ and $b=2$ in the
experimentally performed ranges of $T$ and $v$. Experiments in very low
temperature range are required to determine the exponent $b$.
