Quantum interference effect in electron tunneling through a quantum-dot-ring spin valve
<p>Abstract</p> <p>Spin-dependent transport through a quantum-dot (QD) ring coupled to ferromagnetic leads with noncollinear magnetizations is studied theoretically. Tunneling current, current spin polarization and tunnel magnetoresistance (TMR) as functions of the bias voltage and...
