Structural Changes in Ytterbium Ferrite YbFe2O4 in the Temperature Range From–150 °C TO 300 °C

Аннотация

Structural changes and thermal expansion of the iron ferrite sample YbFe₂O₄ of a rhombohedral modification are studied by high-temperature X-ray diffraction and differential thermal analysis. It is demonstrated that no phase transitions are observed in the temperature range from–150 °C to 300 °С. There are only anisotropic changes in unit cell parameters due to changes in Yb–O and Fe–O bond lengths.
