摘要：
X-ray absorption measurements have been performed on Zn1-xMnxO (x=.25 and x=.05) at the Mn K edge under pressure. Mn is in substitution of Zn whatever the composition or the structure. A phase transformation from wurtzite to rocksalt is observed close to 8 GPa. for both compositions. The local compressibility around the Mn atom is similar to the bulk one, in the wurtzite and in the rocksalt phases. The transition is reversible for x=0.05 but irreversible for x=0.25.
