In this work, we report the production of nonstoichiometric cobalt gallate nanoparticles (Co–Ga NPs) with larger inversion parameters that resulted in enhanced magnetic properties compared to previous studies. The synthesis of nonstoichiometric nanoparticles was realized by a supercritical hydrothermal process and without performing calcination at a high temperature which tended to synthesize thermodynamically stable stoichiometric products. We synthesized nonstoichiometric Co–Ga NPs with a controllable Co/Ga molar ratio, morphology, and particle size at different pH values of the precursor solutions. By applying X-ray absorption fine structure analysis at Ga K-edge, Co K-edge, and Rietveld refinement, nonstoichiometric Co–Ga NPs were found to have large numbers of cobalt atoms occupying octahedral sites compared to CoGa2O4. Their superparamagnetic behavior with enhanced spontaneous magnetization at room temperature owing to percolated superexchange interaction of JBB was observed for the first time. We also proposed a possible formation mechanism of nonstoichiometric Co–Ga NPs from cobalt gallium nitrate layered double hydroxides in the precursor solutions.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "ACS Publications", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1021/acs.cgd.2c01435", "subitem_relation_type_select": "DOI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "This document is the Accepted Manuscript version of a Published Work that appeared in final form in [Crystal Growth \u0026 Design], copyright © American Chemical Society after peer review and technical editing by the publisher.
