Description

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 TtL21/B2 for the Co2TiGa alloy. The Curie temperature TC 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.
