摘要：

Samples from the mixed oxide system YCr1-xFexO3 (0 <= x <= 1) were prepared by self-propagation combustion techniques and studied by neutron and X-ray diffraction at 290 K and by magnetic measurements in the range 2-800 K. The average observed metal-oxygen distances based on refinements in the space group Pnma are in agreement with the expected distances from the valence bond approach. The non-collinear spin arrangement (mode Gamma 4) of YFeO3 and YCrO3 is preserved for the rest (x >= 0.33) of the compounds magnetic at 290 K. The findings indicate that YCrO3 and YFeO3 form a solid solution with strongly frustrated magnetic interactions.
