Query: Spin transport in a lateral spin valve with a suspended Cu channel   We study spin transport through a suspended Cu channel by an electrical
non-local 4-terminal measurement for future spin mechanics applications. A
magnetoresistance due to spin transport through the suspended Cu channel is
observed, and its magnitude is comparable to that of a conventional fixed Cu
lateral spin valve. The spin diffusion length in the suspended Cu channel is
estimated to be 340 nm at room temperature from the spin signal dependence on
the distance between the ferromagnetic injector and detector electrodes. This
value is found to be slightly shorter than in a fixed Cu. The decrease in the
spin diffusion length in the suspended Cu channel is attributed to an increase
in spin scattering originating from naturally oxidized Cu at the bottom of the
Cu channel.
