Experimental realization of a ballistic spin interferometer based on the Rashba effect using a nanolithographically defined square loop array

Takaaki Koga, Yoshiaki Sekine, Junsaku Nitta

The gate-controlled electron spin interference was observed in nanolithographically defined square loop (SL) arrays fabricated using In${}_{0.52}$Al${}_{0.48}$As/In${}_{0.53}$Ga${}_{0.47}$…
