Good Agreement

The temperature and the disorder dependence of the magnetic susceptibility of electrons interacting with spin fluctuations has been calculated. The system is considered to be two-dimensional and the dynamical susceptibility correspond to a strongly correlated electron system in the presence of weak disorder. We obtain deviations from Pauli paramagnetism which are in good agreement with experimental data.
