We synthesized well-crystallized ilmenite-type FeGeO3to investigate its structural and magnetic properties. Ilmenite-type FeGeO3were synthesized by high-pressure synthesis technique using a Kawai-type multi-anvil apparatus. Their structural and magnetic properties were examined by XRD analysis with Rietveld refinement, transmission electron microscopy, Mössbauer spectroscopy and SQUID-magnetization measurements. The subsequent annealing after the high-pressure synthesis was effective to improve the crystallinity of the ilmenite-type FeGeO3. The primary particle size of ilmenite-type FeGeO3was ∼15nm. Some particles seemed to be covered with non- or poorly crystalline phase even after the annealing, and others showed a lamellar microstructure parallel to the (001) plane. Theilmenite-type FeGeO3showed typical antiferromagnetic behavior with the Néel temperature of 79K.
