Structural, electrical and magnetic properties of Ni–Co–Cu–Mn ferrite thick films

Structural, Dielectric, and Magnetic Properties of SCS-Produced Copper Zinc Nanoferrites

“…The plots in Fig. 4 are close to linear thus confirming low polarontype conductivity [17][18][19][20][21][22]. At higher ω, the hopping cannot follow the applied field and lags behind, thus leading to a decrease in σ.…”

“…The charges are often separated over a considerable distance and the contribution to dielectric loss can therefore be orders of magnitude larger than the dielectric response due to molecular fluctuations. The dissipation of power in material is directly proportional to dielectric loss factor [16][17][18][19][20][21][22][23][24].…”

Increased sensibility of mixed ferrite humidity sensors by subsequent heat treatment

“…They have great potential for applications in medicine, for hyperthermia treatment, controlled drug delivery and biosensors, electronics, as humidity or gas sensor, magnetic field sensors, inductors and high frequency applications, as well as applications as catalysts and photocatalysts for various reactions or the removal of undesired pollutants . As a response to the large demand numerous techniques have been employed to obtained ferrites in nanoparticle form, thin and thick films, or controlled morphology such as nanocubes and nanorods . Most commonly used synthesis methods are the ceramic method, in solution syntheses, sol‐gel methods and laser ablation or RF sputtering for thin and thick layer formulations …”
