We study the effect of various configurations of vacancies on the magneticproperties of graphene nanoflake (GNF) with screened realistic long-rangeelectron interaction [T. O. Wehling, et. al., Phys. Rev. Lett. 106, 236805(2011)] within the functional renormalization group approach. In agreement withprevious studies, the presence of vacancies in GNF yields to a strongenhancement of spin-density-wave (SDW) correlations. We show however that onlysome part of the considered configurations of vacancies posses SDW groundstate. The probability of a system with a random configuration of vacancies tobe in the SDW ground state increases with increase of vacancy concentration.The disorder-averaged sublattice magnetization increases linearly with theconcentration of vacancies. The ratio of the sublattice magnetizations at thecenter and edges of GNF, averaged over various realizations of disorder,depends only weakly on the number of vacancies. The effects of vacancies on thelinear conductance and charge properties of GNF are discussed.
