Phys. Rev. Lett. 98, 220501 (2007) [4 pages]Efficient Dynamic Nuclear Polarization at High Magnetic FieldsSee Also: Erratum Received 21 November 2006; published 31 May 2007 By applying a new technique for dynamic nuclear polarization involving simultaneous excitation of electronic and nuclear transitions, we have enhanced the nuclear polarization of the nitrogen nuclei in 15N@C60 by a factor of 103 at a fixed temperature of 3 K and a magnetic field of 8.6 T, more than twice the maximum enhancement reported to date. This methodology will allow the initialization of the nuclear qubit in schemes exploiting N@C60 molecules as components of a quantum information processing device. © 2007 The American Physical Society URL:
