Abstract: Double perovskite oxides REEuCr2O6(RE=La, Pr, Nd, Sm, Gd ,Tb ,Dy, Ho,Er, Tm)were prepared by solid state reaction method.The measurement of XRD, IRand 151Eu Mössbauer spectra show that all samples are orthorhombic structure; as the atomic number of REincreases, the cell volumes decrease.The relationship between isomer shift and Vis linear,Quadrupole splits are negative,and with atomic number of REincreasing,their absolute values increase.

Key words: Double perovskite oxide, REEuCr2O6, 151Eu Mö, ssbauer spectrum, Isomer shift
