Cobalt ferrite, an anomaly among the other spinel ferrites, have continuously captured the consideration of various researchers across the different disciplines due to its inimitable traits and characteristics. In contrast to their spinel ferrite counterparts, the cobalt ferrite exhibits high coercivity, excellent dielectric properties, and significant catalytic behavior, making it a subject of intense investigation and exploration. Despite the extensive research that has been conducted on the cobalt ferrites, there is still no available comprehensive and definitive explanation regarding their structural, magnetic, dielectric, and catalytic traits. Consequently, here the aim is to consolidate and present the potential applicability of cobalt ferrite, while simultaneously drawing the connections to the properties of cobalt ferrite. This comprehensive review aims to elucidate the intricate structural dynamics of cobalt ferrite, and the complexities of its inverse characteristics. The profound implications of inverse nature of cobalt ferrite on its magnetic, catalytic, and dielectric behaviors has also been analysed. Furthermore, this review will also prove helpful for the researchers exploring the potential usage of cobalt ferrites for various applications, thus improving the basic understating of cobalt ferrite behavior. •This review discusses how the inverse nature controls the structural, magnetic, and catalytic properties.•High coercivity, excellent dielectric, and catalytic behavior of cobalt ferrites are reviewed.•A comparison of synthesis parameters like dopants and heat treatment affecting cobalt ferrite properties are discussed.•The cobalt ferrites are reviewed for various applications, viz., high-frequency electronics and environmental solutions.
