Research Abstract

It has been predicted that organic materials consisting of light elements have long spin relaxation time owing to their weak spin-orbit interaction. In this study, we prepared spin valve devices based on molecular conductors, instead of commonly used organic semiconductors. The spin relaxation time was evaluated to be longer than those inaluminum, copper, and graphene.
