Introduction
The Indium Iron Oxide Sputtering Target (InFe₂O₄) is a functional oxide target belonging to the spinel-type oxide family, attracting growing interest in advanced thin-film research and emerging electronic applications. By combining the electrical characteristics of indium-based oxides with the magnetic and catalytic properties of iron oxides, InFe₂O₄ enables the deposition of multifunctional oxide films with tunable electrical, optical, and magnetic behavior.
This material is particularly valuable for research laboratories and advanced manufacturing environments exploring next-generation transparent electronics, spintronic devices, and functional oxide coatings.
Detailed Description
Indium Iron Oxide (InFe₂O₄) sputtering targets are typically fabricated using high-purity indium oxide and iron oxide precursor powders, processed through controlled solid-state reaction, calcination, and high-density sintering. The resulting ceramic target exhibits a dense microstructure, stable stoichiometry, and uniform elemental distribution—critical factors for consistent sputtering performance.
The spinel structure of InFe₂O₄ plays a key role in determining thin-film properties. During magnetron sputtering, this structure supports stable plasma interaction and predictable sputtering rates, enabling good film thickness control and compositional uniformity. Compared with simple binary oxides, InFe₂O₄ allows engineers to fine-tune film conductivity, carrier concentration, and magnetic response by adjusting deposition parameters such as oxygen partial pressure, substrate temperature, and post-deposition annealing.
Targets are available in a wide range of diameters and thicknesses, and can be supplied with or without metallic backing plates depending on power density and thermal management requirements.

Indium Iron Oxide sputtering targets are mainly used in advanced R&D and pilot-scale production, including:
Functional oxide thin films for electronic and optoelectronic devices
Spintronic and magneto-electronic research
Transparent or semi-transparent conductive oxide studies
Sensor materials (gas, magnetic, or multifunctional sensors)
Catalytic and electrochemical thin-film coatings
Academic and industrial materials science research
