Effect of intrinsic spin relaxation on the spin-dependent cotunneling transport through quantum dots
Effect of intrinsic spin relaxation on the spin-dependent cotunneling transport through quantum dots
Spin-polarized transport through quantum dots is analyzed theoretically in the cotunneling regime. It is shown that the zero-bias anomaly, found recently in the antiparallel configuration, can also exist in the case when one electrode is magnetic while the other one is nonmagnetic. The physical mechanism of the anomaly is also …
