Quantum mechanism of nonlocal Gilbert damping in magnetic trilayers

A fully quantum-mechanical calculation of the Gilbert damping constant alpha in magnetic trilayers is done by employing the torque-correlation formula within a realistic tight-binding model. A remarkable enhancement of alpha in Co/NM sub(1)/NM sub(2) trilayers is obtained due to adding the caps NM s...
