Absence of hyperfine effects in ${}^{13}$C-graphene spin valve devices

M. Wojtaszek, I. J. Vera-Marun, E. Whiteway +2

The carbon isotope ${}^{13}$C, in contrast to ${}^{12}$C, possesses a nuclear magnetic moment and can induce electron spin dephasing in graphene. This effect is usually neglected due t…
