Abstract: We investigated the transport properties of ferromagnetic/semiconductor hybrid two-terminal structures utilizing an In_<0.75>Ga_<0.25>As/In_<0.75>Al_<0.25>As 2DEG formed on a GaAs (001) substrate with In_xAl_<1-x>As step-graded buffer layers. We used NiFe as ferromagnetic electrodes for injection/detection of spin-polarized electrons, which were formed on side walls of the semiconductor mesa to contact electron channel directly. We measured spin valve properties at low temperatures, and successfully found clear spin valve signals as well as clear channel width dependence. The results with such clear dependence suggest successful spin transport in the present samples.
