Synchrotron-excited resonant Mossbauer study of magnetic properties under pressure up to 80 GPa

Electrical resistivity study of CeZn11: Magnetic field and pressure phase diagram up to 5 GPa

Thorough resistivity measurements on single crystals of CeZn 11 under pressure p and magnetic field H are presented. At ambient pressure, CeZn 11 orders antiferromagnetically at T N = 2 K. The pressure dependence of the resistivity reveals an increase of the Kondo effect. We determine the pressure evolution of the magnetic exchange interaction between conduction and localized 4f electrons. It q...

A synchrotron Mössbauer spectroscopy study of (Mg,Fe)SiO3 perovskite up to 120 GPa

The electronic environment of the Fe nuclei in two silicate perovskite samples, Fe0.05Mg0.95SiO3 (Pv05) and Fe0.1Mg0.9SiO3 (Pv10), have been measured to 120 GPa and 75 GPa, respectively, at room temperature using diamond anvil cells and synchrotron Mössbauer spectroscopy (SMS). Such investigations of extremely small and dilute Fe-bearing samples have become possible through the development of S...
