EuFeO3 perovskite has been studied by using 57Fe Mössbauer effect and X-ray diffraction under pressures up to 90 GPa and in the temperature range of 4.2–300 K. A high-pressure-induced first-order phase transition is observed in the pressure range of 45–52 GPa as manifested by a discontinuous volume and IS reduction and dramatic changes of the hyperfine interaction parameters. The high-pressure phase of Fe3+ is established as a low-spin state (S=1/2, 2T2g) characterized by spin-spin magnetic relaxation spectra to the lowest temperature. The nature and mechanism of the magnetic relaxation are discussed.
