Spin Injection and Relaxation in a Mesoscopic Superconductor
Spin Injection and Relaxation in a Mesoscopic Superconductor
We study spin accumulation and spin relaxation in a superconducting nanowire. Spins are injected and detected by using a set of magnetic tunnel contact electrodes, closely spaced along the nanowire. We observe a giant enhancement of the spin accumulation of up to five orders of magnitude on transition into the …
