Research Abstract	Japan with a very little resources has done the industrial production as importing raw materials from other countries. On the other hand, many magnetic materials have been usedin many industrial products. Since the production of magnetic materials requires conventionally more energy, it has led to high cost. When producing the magnetic materials comparable to conventional ones, it will be possible low-cost process by reducing the number of steps. We designed a method that can be changeable to the magnetic materials immediately after "combustion synthesis", known as a low cost material preparation method, in strong magnetic field. In this study, the novel method was carried out, and the obtained materials were evaluated their magnetic properties. As a result, in Ticonal alloy composition added of higher heat of formation of Ti+C, relatively good properties were observed. But its properties did not reach to commercially available one. therefore there is room for further consideration.
