“…In addition, sodium hydroxide solution is often used, particularly in coprecipitation and hydrothermal processes, resulting in introduction of slight amount of Na impurity in ZMFO. For fabricating ZMFO thin films, physical vapor deposition techniques, such as sputtering 19 and pulsed laser deposition, 20 are widely used. Even though they are capable of growing phase‐pure ZMFO films with high density, they are generally complex in implementation, costly in instrumentation owing to the delicate electronic and high‐vacuum systems, as well as less amenable to doping in general.…”

ZnxMn1−xFe2O4 is a prototypical soft magnetic material, and commonly used for high‐frequency applications due to its low power loss and high permeability and resistivity. Various wet chemistry routes have been developed for synthesizing ZnxMn1−xFe2O4; however, multistep procedures are usually involved in these methods, making them complex in implementation. Here, we use a facile chelate method to prepare ZnxMn1−xFe2O4 sol precursor for fabricating both fine powders and nanocrystalline thin films. X‐ray diffraction and electron microscopy techniques are used to characterize the microstructure and composition of as‐synthesized ZnxMn1−xFe2O4, and superconducting quantum interface device is used to measure their magnetic properties. The investigation of powders with different Zn/Mn cation concentration indicates that the saturation magnetization is determined by the content parameter x; while the coercive field is closely correlated to the crystal size. Further, Zn0.4Mn0.6Fe2O4 thin films were deposited using spin‐coating technique, and annealed at different temperatures to study the formation of the impurity phase.
