Query: Spin relaxation 1/f noise in graphene   We report the first measurement of 1/f type noise associated with electronic
spin transport, using single layer graphene as a prototypical material with a
large and tunable Hooge parameter. We identify the presence of two
contributions to the measured spin-dependent noise: contact polarization noise
from the ferromagnetic electrodes, which can be filtered out using the
cross-correlation method, and the noise originated from the spin relaxation
processes. The noise magnitude for spin and charge transport differs by three
orders of magnitude, implying different scattering mechanisms for the 1/f
fluctuations in the charge and spin transport processes. A modulation of the
spin-dependent noise magnitude by changing the spin relaxation length and time
indicates that the spin-flip processes dominate the spin-dependent noise.
