The magnetic susceptibility of Hg0.95Mn0.05S and Hg0.90Mn0.10S was measured by the SQUID technique. The experimental data were compared with the extended nearest neighbour pair approximation (ENNPA) calculation. The long range exchange interaction J=JNNR-n, with the exponent n=4, was found for both samples. The nearest neighbour exchange integral JNN was found to be around two times smaller than the effective exchange integral Jeff. The small value of the exponent n, which is a characteristic of the narrow gap semimagnetic semiconductors (SMSC's), as well as the small JNN/Jeff ratio, show the importance of a long-range exchange mechanism.
