The magnetic properties of the Mn3Ga(1-x)SnxC, 0 ≤ x ≤ 1 antiperovskite compounds have been investigated in detail. Though all compounds of this series crystallize in a cubic structure, the Ga rich (x ≤ 0.2) compounds transform, via a first order transformation, to an antiferromagnetic ground state and the Sn rich (x ≥ 0.8) compounds exhibit dominant ferromagnetic interactions at low temperature. In the intermediate range (0.4 ≤ x ≤ 0.7) co-existence of ferromagnetic and antiferromagnetic interactions can be seen. The results have been explained to be due to growth of ferromagnetic sub-lattice at the expense of antiferromagnetic sub-lattice with increasing Sn concentration in Mn3Ga(1-x)SnxC. This growth occurs to a point where the first-order transition is altered from a ferromagnetic - antiferromagnetic type in Ga rich compounds to a paramagnetic - ferrimagnetic type in Mn3SnC.
