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., 日本応用物理学会講演会}, title = {Electronic and magnetic properties of graphene/Co2Fe(Ge0.5Ga0.5) Heusler alloy heterostructure}, year = {2019} }
