| Outline of Final Research Achievements |
An original technique to synthesize metal fluorides easily has been developed by using a high pressure generation apparatus. We have successfully synthesized single phases of rutile-type (Mg1-xMnx)F2 (0≦x≦0.50 and 0.95≦x≦1) and so on. It is found that the increase of synthesis pressure makes the single phase composition region narrow. Then, their magnetic properties have been investigated and the phase diagram of the solid solutions has been decided. Besides, we have also successfully synthesized single phases of (Ti1-xMnx)(O1-xFx)2 by using the same synthesis technique. In addition, we have applied it to synthesize metal sulfides and so on which are easily decomposed at high temperatures and ambient pressure as well as metal fluorides, and succeeded in synthesizing high quality single phase samples.
