Outline of Final Research Achievements

In this study, we have tried fabricating spin gapless semiconductors (SGS), which have fully spin polarized and high mobility carriers, and finding the way for use SGS as novel spintronic devices. We found that Mn2CoAl (MCA) is the most promising candidate of SGS, and high quality films of MCA can be obtained by ion-beam assisted sputtering. We also showed that MCA is promising as a novel spin source of both spin-polarized electrons and holes.
