Impact of Trivalent Metal Ion Doping on Structural, Photoluminescence and Electric Properties of NiFe2O4 Thin Films

Recent Advances in Spinel Ferrite-Based Thin Films: Synthesis, Performances, Applications, and Beyond

“…It is worth noting that some spinel ferrite-based thin films exhibited unique optical characteristics, such as absorption, optical bands, birefringence, and Faraday rotation, which have been adopted for magneto-optical recording devices and photocatalysts (Li et al, 2010;Bharathi et al, 2011;Chen et al, 2017;Chavan et al, 2019;Henning et al, 2019;Yu et al, 2019;Labchir et al, 2020;Lan et al, 2020;Choueikani et al, 2021). For example, low index magneto-optical CoFe 2 O 4silica nanocomposite thin films were fabricated using the composite method and presented an intrinsic Faraday rotation of 310 °/cm at 1,550 nm for an NP 1.5% volume fraction, and the modal birefringence was the order of 10 -4 (Choueikani et al, 2021).…”

Influence of trivalent Cr ion substitution on the physicochemical, optical, electrical, and dielectric properties of sprayed NiFe2O4 spinel-magnetic thin films

“…The variation in resistivity as a function of temperature conrms the Arrhenius relation. 65 Using the DCR plots, the activation energy DE for each sample in the ferrimagnetic and paramagnetic locale was determined. The estimated activation energies for the all Cr 3+substituted nickel spinel ferrite samples are presented in Table 3.…”

Structural, Optical and Magnetic Properties of Diamagnetic Cd2+ Incorporated Cobalt Ferrite Thin Films Deposited by Spray Pyrolysis

“…The band nearby 1550 cm −1 resembles anti-symmetric NO 3 elongating vibrations and the band at 1647 cm −1 corresponds to carboxylate anions. 69 The stretching vibration at 2350 cm −1 corresponds to the hydroxyl group. The visibility of absorption bands in the infrared spectra rests on the distribution and type of cations amongst octahedral and tetrahedral sites.…”
