The MTJ shows clear hysteretic tunnel magnetoresistance (TMR) effect, which is evidence for spin transport through a single semiconductor QD. The TMR ratio and the curve shapes are varied by changing the gate voltage.","authors_text":"K. Hamaya, K. Hirakawa, K. Shibata, M. Jung, M. Kawamura, S. Ishida, S. Masubuchi, T. Machida, T.
