Significant modulation of electrical spin accumulation by efficient thermal spin injection

We have investigated the dc bias current dependence of the nonlocal spin valve signal in CoFeAl/Cu lateral spin valves. The spin signal is found to increase monotonically with the bias current. Surprisingly, the modulation amplitude from -1 mA to 1 mA exceeds 30 percent of the spin signal at low bia...
