Abstract
Starting from the model of Casimir and Du Pré, which has been refined by Eisenstein, an expression for the differential paramagnetic susceptibility of a paramagnetic material, placed in a (gaseous or liquid) bath, is derived. This expression contains among others the coefficient of heat conduction and heat capacity of the surroundings and a heat resistance between sample and bath.
Numerical analysis and a short comparison with experiments show that in the temperature region of liquid helium the above-mentioned quantities have a remarkable influence on the dispersion and absorption curves.
