Schematics of the electrical 3TH measurement and the spin relaxation in a semiconductor (a). The plot of normalized spin accumulation voltage vs. of Fe₃O₄/MgO/GaAs, Fe₃O₄/GaAs, Fe₃O₄/MgO/Si, and Fe/MgO/GaAs devices showing the Verwey transition (shaded region) coinciding exactly the region of enhancement in (b) while the normalized value of local 2-probe voltages as a function of for this sample is plotted for comparison (c) [7].
