Structural Studies of Synthetic Ferromagnetic Sample CeTiGe3 Under Pressure*

Under extreme conditions the interactions, and thereby the arrangement of atoms, in materials is affected. We can change the temperature and pressure which a material is experiencing to observe what changes occur; such as structural changes, magnetic property changes, and in some cases superconductivity. This research was a case study of CeTiGe3, a ferromagnetic material, under extreme pressures using helium as pressure transmitting medium. The measurements were conducted under pressure using single crystal x-ray diffraction in a synchrotron. No phase transitions were observed, but structural shifts were seen at ambient temperature with increased pressure from ~0-10 GPa. Further investigations of the magnetic properties of CeTiGe3 can be carried out to relate structural properties to magnetic properties.
