Abstract:The differential conductivity (dI/dV) spectra of Fe(001) film,
together with the topographic image,
were measured at room temperature
using ferromagnetic Fe and non-magnetic W probe tips.
A narrow peak was observed at 0.3 V in the dI/dV spectrum using a W tip,
which coincides with the surface state in the minority spin band predicted
by a theoretical calculation.
On the other hand, we found a pronounced peak at 0.7 V
in the tunneling spectra using a Fe-evaporated probe tip

“…Both spectra in Fig. 3e show two distinct peaks at À0.54 and +0.27 V [18,19], respectively. There is no significant difference between the two spectra.…”
