The BaIr{sub 1-x}Mn{sub x}O{sub 3} (0.0<=x<=1.0) solid solutions were synthesized by using the solid-state chemical method and high pressure sintering in the pressure range 0-5 GPa. According to the pressure-composition 'phase diagram' at 1000 deg. C, the 9M BaIr{sub 1-x}Mn{sub x}O{sub 3} transforms to the 6M form at 5 GPa and x<=1/6. In the x range 0.5-1.0, it transforms to the 9R form in a large pressure range. For the 9M BaIrO{sub 3}, the Mn ions substitution for Ir ions enhances the semiconducting property, and reduces the weak ferromagnetism. When x is larger than 1/3, the 9M/9R BaIr{sub 1-x}Mn{sub x}O{sub 3} behave spin-glass-like state at low temperature, with the glass transition temperature T{sub g} about 60 K. For the 6M BaIrO{sub 3}, the Mn ions doping results in that it transforms to insulator and spin-glass-like magnetism from the initial paramagnetic metal. - Graphical abstract: The BaRu{sub 1-x}Mn{sub x}O{sub 3} solid solutions were synthesized by using the solid-state chemical method and high-pressure sintering, and the pressure-composition 'phase diagram' at 1000 deg. C was obtained.
