| Research Abstract |
In the present research, we have tried to extend our nanoscale transport measurement technique to spin transport. First, we developed a method to make a magnetic probe by coating CoFe on cabon nanotube (CNT) tips. Using these magnetic probes in our four-tip scanning tunneling microscope, we succeeded in detecting some spin signal, which is likely originated from the current-induced spin-polarization phenomenon in surface states of ultrathin bismuth films.
