Structural and Magnetic Properties of Fe-Diluted Si Alloy Films by Pulsed-Laser Deposition

Abstract

Fe-diluted Si alloys grown on p-type Si (100) substrates by pulsed-laser deposition method were studied for tructural, electrical, and magnetic properties. The X-ray diffraction patterns for these alloy samples showed a few of peaks with cubic structures such as FeSi, The manipulation of electron spin in semiconductors with transition metals is very important.The efficiency of electron spin injection is still deficient in major problems as low as a few % for the realization of spin field effect transistors, which is contributed by the conductance mismatch of junctions between metal and semiconductor. Diluted magnetic semiconductor (DMS) is known to be a useful way to
