This predicted magnetic ground state has a clear spectroscopic signature - a silicon step-edge state at 0.5 eV above the Fermi level - that arises from strong exchange splitting and hence would not occur without spin polarization. Here we report spatially resolved scanning tunneling spectroscopy data for these nanowires.
