Implication

Experimental study reveals spin-memory loss and spin-diffusion lengths in sputtered palladium and platinum junctions, highlighting significant spin depolarization at copper interfaces.

Key Points

To determine the low-temperature spin-diffusion lengths of sputtered palladium and platinum and quantify spin-memory loss at their respective interfaces with copper.
Characterized sputtered thin films and multilayer junctions of Pd, Pt, and Cu at 4.2 K.
Calculated spin-diffusion lengths, interface specific resistances, and interfacial spin-memory loss parameters, comparing findings to neighboring periodic table transition metals (Nb and W).
Spin-diffusion lengths at 4.2 K were 25 (+10/-5) nm for sputtered Pd and 14 ± 6 nm for sputtered Pt.
Interface specific resistances were measured at 0.9 ± 0.1 fΩ m² for Pd/Cu and 1.5 ± 0.1 fΩ m² for Pt/Cu.
Spin-memory loss parameters were determined to be 0.24 (+0.06/-0.03) at Pd/Cu interfaces and 0.9 ± 0.1 at Pt/Cu interfaces.
