Pressure dependence of electronic, magnetic, and structural properties of EuPd3S4. The pressure dependence of (A) AFM transition temperature TN, (B) resistance at 1.8 K, (C) unit cell volume estimated from the high-pressure X-ray diffraction measurement, (D) mean valence estimated from the Synchrotron Mössbauer spectroscopy (SMS) spectra, and (E) mean valence estimated from the partial fluorescence-yield X-ray absorption spectroscopy (PFY-XAS) spectra. PTM: pressure transmitting medium. RT: room temperature. The blue dashed curve in (C) is the second-order BM EOS fitted curve that shows the clear difference in the unit cell volume between zone I and zone III. The vertical dashed lines crossing all panels mark the lower and upper boundaries of the two-phase region determined from X-ray diffraction.
