Local long-distance spin transport in single layer graphene spin filter

Spin transport through single layer graphene grown by chemical vapor deposition has been measured in the local measurement configuration using aluminum oxide tunnel barriers and Co electrodes. Unlike the case of non-local measurements we report positive magnetoresistance for graphene channels as lon...

Unlike the case of non-local measurements we report positive magnetoresistance for graphene channels as long as 10 microns at room temperature.
