Using the test Hamiltonian introduced by Dichtel, Jelitto, and Koppe we calculated the linear response of the model to a small magnetic field, and determined therefrom the static susceptibility for the case of an s. c. lattice. Numerical results were obtained for this type of lattice. The susceptibility is found to be rather independent of temperature in a wide range of absolute temperature. The ratio of the diamagnetic to the paramagnetic susceptibility (which was calculated in a previous… CONTINUE READING
