Abstract :
A MnSiC compound with a Curie temperature above room temperature is synthesized using the carbonization technique. EDX and EXAFS measurements indicate that the host manganese silicide is Mn4Si7. Carbonization is found to play an important role in the observed ferromagnetism and anomalous Hall effect although no effect of carbon on the structure is detected.
