abstract = "In order to improve the hard magnetic properties of MnAl alloy, it is critical to fabricate fine phase MnAl powders. In addition, a rapid cooling process and an addition of stabilization elements are required to fabricate a homogeneous phase because a phase
is a metastable structure. In this study, -Mn54Al46x
C
x
(x = 0, 1, 2) powders were prepared by melt-spinning and subsequent annealing and milling processes. As a result, a main phase was revealed as a high temperature
phase in melt spun MnAl ribbons. And a subsequent annealing in the temperature range of 450650 \textdegreeC resulted in the formation of a phase. A maximum saturation magnetization (M
s) value of 96.56 emu/g was obtained when the melt-spun -Mn54Al44C2
ribbons were annealed at 500 \textdegreeC for 10 min. However, a milling process increased the coercivity up to 3804 Oe but simultaneously reduced M
s down to 60.34 emu/g.",
