Figure 12.

Number of resistive states for SR5, calculated from the I-V curves, during the current sweep-up ($N^{\uparrow }$) and sweep-down ($N^{\downarrow }$). Near to $T\simeq 9$ K, $N^{\uparrow }$ and $N^{\downarrow }$ suddenly converge, assuming the same value at $T\ge 9$ K. Broken lines are guides for the eye.
