Abstract
This review provides a comprehensive overview of the recent advances in the various typical spinel ferrite-based thin films with controlled synthesis, their performances, applications in multifunctional material fields, fundamental scientific challenges, and beyond. Firstly, the crystal structures of spinel ferrite-based thin films are introduced. Secondly, recent progress in traditional synthesizing and novel methods for preparation of spinel ferrite-based films are highlighted. Thirdly, their magnetism, electricity, optics performances, and applications in advanced information technology, energy storage and conversion, and environmental conservation fields are also summarized and discussed in-depth. Some effective strategies for optimizing performances and further applications are summarized. Finally, the present review work ends with a short discussion concerning the challenges, opportunities, and future prospects of spinel ferrite-based thin films.
Highlights
Spinel materials are made of a general formulation of AB2O4, where the A and B are metal ions and comprise of A-O tetrahedron and B-O octahedron
During the development of spinel ferrite-based thin films synthesis, some other innovative technologies can be adopted such as ultrasound-assisted sol-gel, metallo-organic decomposition, and dip-coating methods, etc
Recent efforts have been focused on investigating the electrochemical performance of spinel ferrite-based thin films as both anodes and cathodes for rechargeable lithium-ion and aqueous batteries (Cheng et al, 2012; Wang et al, 2013; Wang et al, 2015; Hwang et al, 2017; Choi et al, 2018; Das et al, 2018; Huang et al, 2020; Dongale et al, 2021)
