Curie law in diamagnetic susceptibility
Volkov B.A., Kopaev Yu.V., Tugushev V.V.
The magnetic susceptibility of systems that are unstable to electron-hole pairing is investigated in the self-consistent-field approximation. It is shown that the response of the system is diamagnetic, and that its temperature dependence obeys the Curie law in the case of an imaginary order parameter.
