Spin injection by spin–charge coupling in proximity induced magnetic graphene

Abstract Within the field of spintronics major efforts are directed towards developing applications for spin-based transport devices made fully out two-dimensional materials. In this work we present an experimental realization a spin-valve device where generation spin signal is exclusively attributed to spin-dependent conductivity magnetic graphene resulting from proximity interlayer antiferromagnet, chromium sulfide bromide (CrSBr). We clearly demonstrate that usage conventional air-sensitive 3D contacts can be avoided when graphene/CrSBr heterostructures employed. Moreover, apart providing exceptionally long relaxation length, both and allows automatically avoid mismatch between source channel circuits has considered using low-resistive contacts. Our results address necessary step in engineering spintronic circuitry layered materials precede further developments area complex spin-logic devices. introduce fabrication procedure designed implemented recipe preparation electrodes via damage-free technique offers immediate advantage fields delicate organic
