Popis: Study of the anomalous behavior of the linear thermal expansion coefficient near the antiferromagnetic phase transitions in iron borate crystals FeBO3 are reported. The lattice parameters and volume of FeBO3 have been measured in the temperature range 25–300˚C by the X-ray diffraction method. The thermal expansion is evidently sharply anisotropic and spike near the Néel temperature.
