Abstract :
Pure bcc β-phase, fcc γ-phase and hcp phase of Fe-Mn-Ga system have been obtained by melt spinning method and subsequent anneal. It is found that there is a rapid phase transition from β and γ-phase to hcp phase. The β-phase shows a typical low temperature ferromagnetic property, while γ-phase shows a ferromagnetic to antiferromagnetic transition. The newly found hcp phase shows a good ferromagnetic behavior with a relatively high TC, which makes it a possible candidate for hard magnetic material.
