Abstract

Microstructural analysis was performed for Mn-Bi prepared by in-field solid-phase reactive sintering, in order to investigate the origin of magnetic field effects on the reaction. The number of formed MnBi phase around Mn grain in 10 T was almost 3 times larger than that in a zero field. The results indicated that the magnetic field enhanced the phase formation rate of MnBi phase. Due to the enhancement of the phase formation rate, the fraction of MnBi phase was drastically increased by in-field annealing.
