This book chapter provides a comprehensive overview of the properties of soft nanoferrites, highlighting their unique characteristics and potential applications across various fields. Soft nanoferrites exhibit magnetic softness with low coercivity and remanence, enabling reversible magnetization changes crucial for applications in electronics and data storage. The tunability of their magnetic properties, achieved through size-dependent effects, surface modifications, and compositional adjustments, allows for customization to meet specific application requirements. The high surface area of soft nanoferrites influences their reactivity, catalytic capabilities, and adsorption capacity, making them versatile for applications in catalysis and environmental remediation. Biocompatibility considerations, achieved through surface functionalization, open avenues for biomedical applications such as drug delivery, hyperthermia treatments, and imaging. The ability of soft nanoferrites to respond to external stimuli, such as magnetic fields or changes in pH, adds functionality, enabling applications in sensors and actuators. Thermal stability considerations are crucial for applications involving exposure to elevated temperatures. Achieving colloidal stability and dispersibility is essential for applications in biomedical and nanotechnological fields. With their diverse properties, soft nanoferrites find applications in electronics, data storage, catalysis, biomedical imaging, drug delivery, and magnetic hyperthermia, paving the way for further advancements in materials science and technology.
