Consistent perturbation theory for thermodynamical quantities in type-II superconductors in magnetic field at low temperatures is developed. It is complementary to the existing expansion valid at high temperatures. Magnetization and specific heat are calculated to two-loop order and compare well to existing Monte Carlo simulations and experiments.
