| 内容記述 | As a zero-gap semiconductor with a pin-hole free nature, graphene was proposed as an attractive low energy barrier for vertical spin-valves (SV) to solve the trade-off between MR ratio and low RA product usually observed in MgO-based vertical SV. So far, the MR ratio reported in graphene-spacer vertical SV is far below the application level due to the usage of conventional ferromagnetic electrodes (Ni, Co, Fe etc.) with low spin polarization. Utilizing high spin-polarized ferromagnetic electrodes such as full Heusler alloys is potential way to enhance the MR ratio in graphene-spacer SV, however, there is no precedent for success in the growth of graphene on Heusler alloy underlayer. In this study, we report on the demonstration and characterization of a novel heterostructure consisting of single-layer graphene (SLG) synthesized by high-vacuum chemical vapor deposition (CVD) on a half-metallic Co2Fe(Ge0.5Ga0.5) (CFGG) Heusler alloy, which provides a promising building block for developing high performance graphene-spacer vertical SV. | |||||
