The effect of pressure on mechanically alloyed nanostructured Gd3Fe5O12 was investigated using in situ angle-dispersive X-ray diffraction measurements at room temperature. No structural phase transitions were observed, but an anomalous behavior in the volume vs. pressure curve, attributed to nonhydrostatic effects, was observed in the pressure range between 4.4 GPa and 9.1 GPa. The analysis of effect of pressure on the Wickoff 23c sites, occupied by Gd3+ ions, 16a and 24d sites, occupied by Fe3+ ions, and 96h sites, occupied by O2– ions, was performed. The value of the bulk modulus B0 for nanostructured Gd3Fe5O12 could not be determined due to nonhydrostatic effects associated with the silicone oil used as a pressure transmitting medium.
