We measured steady-state ESR of insulator samples of Si:P with the newly made system. DNP effect on ESR spectrum was found at 1.5 K. We also found that the magnitude of the nuclear spin polarization was changed by applying NMR pulses.}, title = {希薄ドープSi:Pの31p核スピン状態観測のためのESR/NMR 二重共鳴システムの開発とESRによる動的核偏極効果の測定}, year = {2012} }
