This study is to perform following three experiments for realization of magnetometry using defects in diamond. (1) We made an electrically detected magnetic resonance system for the realization of the magnetometry. We have not detected electron spins in nitrogen centers but carbon vacancies in diamond. (2) We demonstrated the control of orientations of nitrogen-vacancies in diamond to understand the crystal grown mechanism of diamond crystal doped with nitrogen. We have demonstrated more than 99 % of the NV centers have been aligned along the [111]-axis using a chemical-vapor deposited diamond thin film on a (111)diamond substrate. We also clarified the grown mechanism. (3) We demonstrated the spin-injection into diamond to understand the interaction between impurities in diamond and conduction electrons. We deposited a nickel-iron layer on a diamond substrate, and we have observed the inverse spin-Hall voltage in such a sample.
