摘要：

X-ray diffraction studies carried out on MnCoxSb system revealed that the limiting value of single phase NiAs type crystal structure formation exists upto x=0.25. The variation of lattice parameters 'a' and 'c', magnetization and Curie temperature with increasing Co concentration suggests that the excess Co atoms carry magnetic moment and occupy the interstitial sites. The figure of merit evaluated from the Faraday rotation and the optical absorption coefficient at 6328 angstrom was found to decrease with the increase of Co concentration.
