Abstract

The thermal expansion of Sr₂FeVO_5.6(SFVO) has been measured in the temperature interval 20-300 K by the powder X-ray diffraction technique to elucidate the relationship between the crystal symmetry and its magnetic behaviour. The thermal expansion coefficients α_a, α_b and α_c revealed a sudden decrease at 80 K and 240 K, although the crystal symmetry of the compound remained unchanged. Moreover, for 100 K270 K, a high anisotropy of the thermal expansion was observed. This effect is expected to be related to changes in the magnetic ordering of the compound studied.
