The magnetic properties of Mn 3–x Co x GaC(x≤0.5) are studied in order to investigate the nature of the magnetic order-order phase transitions. The magnetic phase diagram for the transition temperatures versus concentration is determined. On the basis of these results, the relation between the effect of alloying and of pressure on the magnetic transitions of Mn 3−x Co x GaC system is discussed.
