Lp. Li et al., FE-57 MOSSBAUER-SPECTRA STUDY ON EU(0.5)RE(0.5)FE(0.5)MN(0.5)O(3) OXIDES, Physica status solidi. b, Basic research, 187(1), 1995, pp. 225-230
The method of solid state reactions is used to synthesize the samples
of Eu(0.5)RE(0.5)Fe(0.5)Mn(0.50)O(3) (RE = La, Pr, Nd, Sm, Eu, Gd, Tb,
Dy, Ho, Er, Tm, Yb, Y). XRD and Fe-57 Mossbauer spectra are measured.
It is found that the volume of the unit cell of the samples decreases
with increasing atomic number of RE. The Fe ions are in the Fe3+ high
spin state, and the relationship between the quadrupole splittings an
d the lattice distortion parameter D of the samples is linear.
