内容記述 |
Mossbauer spectra of polycrystalline ε-57FeOOH were measured up to 14.6 GPa at room temperature using the energy-domain synchrotron 57Fe Mossbauer source at BL11XU in SPring-8. ε-FeOOH appears to be antiferromagnetic at ambient pressure and temperature based on measurements with/without an external magnetic field. On compression, the quadrupole shift 2ε shifted from negative to positive at ~8 GPa, which is consistent with a magnetic spin rotation. Previous XRD studies did not detect any transitions at this pressure; thus we infer the change in 2ε is the third pressure-induced transition without major structural change in addition to the hydrogen-bond symmetrization and electronic spin transition. |
