Abstract
Magnetic properties and phase stability of the L21 phase in Co2(Ti1-xMnx)Ga alloys were investigated by magnetic and DSC measurements. The order-disorder phase transition temperature from the L21 to the B2 phase TtL21/B2 was found to increase linearly with increasing Ti composition and its linear extrapolation to x = 0.0 accords with the reported value of Tt L21/B2 for the Co2TiGa alloy. The Curie temperature T C increases with increasing Mn composition, exhibiting an upward convexity, but is rather independent of composition in the high Mn region. It is concluded that the Co2(Ti1-xMnx)Ga alloys located in the middle composition range possess both a high TC and a high TtL21/B2.
