| Outline of Final Research Achievements |
Graphene Passivated Ferromagnetic Electrodes (GPFE) device, a type of tunneling magnetoresistive device, is composed of Ni and a graphene layer (G / Ni). G is inert to oxygen, but Ni is easy to oxidize. Also, so far, whether G / Ni is a half-metallic material or not has not been confirmed. In this study, we investigated the oxidation properties and half-metal characteristics of G/Ni and its mechanism by first principles method. The presence of G prevented the oxidation of Ni. Half-metal characteristics of G / Ni were obtained due to G/Ni conformational structure. These results are presented in Physical Society Meetings and are published in academic journals as highlight articles.
