Measurements of pressure effect on magnetic susceptibility of semiconducting SmS. Strong positive pressure effect correlates with behavior of the energy gap of SmS. Excess susceptibility originates from orbital magnetism of band electronic states. The model is verified by calculations of magnetic response of band electronic states.
