In this paper, hydrothermal method was used as the main preparation method to study the preparation and properties of Co-based ferrite. Co-based ferrite nanoparticles with particle sizes between 20-50 nm were prepared by controlling parameters such as hydrothermal reaction time, reaction temperature, and pH value. The morphology, crystallinity, magnetic properties, and electrical properties were characterized, and the results show that the prepared Co-based ferrite nanomaterials have a single crystal phase, good superparamagnetic and ferromagnetic properties, and excellent electrical properties, exhibiting excellent ferroelectric properties. The research shows that Co-based ferrite nanomaterials have good application prospects.Keywords: Co-based ferrite; nanomaterials; hydrothermal preparation; magnetic properties; electrical properties
