Popis:	In situ high pressure energy-dispersive x-ray synchrotron radiation diffraction and resistance experiments are carried out on CaCuMn6O12. Its crystal structure is stable in the measured pressure range. The equation of state of CaCuMn6O12 is obtained from the V/V0−P relationship (V and V0 are the volumes at pressure P and at atmosphere). The bulk modulus B0 is calculated based on the Birch–Murnaghan equation. Low temperature x-ray diffraction shows no phase transition occurring down to 160 K.
