Abstract :
Magneto-structural correlations in Pr0.15Gd0.85Mn2Ge2 have been studied by synchrotron diffraction in the temperature range between 11 and 300 K. This compound crystallizes in the ThCr2Si2-type structure (space group I 4 / mmm ). The unit cell parameters a and c were determined by Rietveld refinements as a function of temperature. Anomalies in the temperature dependence of the unit cell parameters a and c , the c / a ratio and the unit cell volume V at about 240 and 140 K, which is close to the magnetic phase transition temperatures, indicate a pronounced magneto-structural correlation. Spontaneous volume change and linear magnetostrictions are derived as a function of temperature.
