Spin susceptibility of disordered gapped graphene systems

- We calculated the density of states of gapped graphene in the presence of weak disorder.
- We determined the temperature dependence of the static spin susceptibility of graphene systems, and explain qualitatively the recent experimental results.
- We analyzed the effect of several parameters on temperature dependence of the spin susceptibility of graphene systems.

We calculate the spin susceptibility for the case of gapped graphene systems in the presence of disorder. The average single-particle density of states in gapped graphene with disorder was calculated, using the Born and the T-matrix approximations. The temperature dependence of the static spin susceptibility was analyzed. The influence of the chemical potential position and disorder is also discussed.
