Evaluation of spectral, optoelectrical, dielectric, magnetic, and morphological properties of RE3+ (La3+, and Ce3+) and Co2+ co-doped Zn0.75Cu0.25Fe2O4 ferrites

Structural, optical, electrical, dielectric, molecular vibrational and magnetic properties of La3+ doped Mg–Cd–Cu ferrites prepared by Co-precipitation technique

“…Zhou et al, [26] also reported that the maximum limit of the substitution of La 3+ is x = 0.02 then the LaFeO3 phase appeared. [27] reported Zn0.5Co0.25Cu0.25La0.125Fe1.875O4 ferrite and observed the LaFeO3 phase at 33 o . Asma et al, [28] observed that the intensity of LaFeO3 phase in La 3+ doped Mg-Ni-Co-Cu ferrites was increased for La 3+ concentration x = 0.06 to x = 0.15.…”

Estimation of the spectral, electrical, and dielectric properties of Mn-Cu-Cd-Gd ferrite\graphene nanoplatelets composites

“…The remanence and coercivity were minimum for 5wt% concentration of GNPs. The squareness ratio (SQ = Mr/Ms) [22] for MCCFG/GNPs ferrite and their composites was also reduced with the addition of GNPs in the MCCFG sample. By the employment of the following relations of magneto crystalline anisotropic constant (K), and initial permeability (µ i ), were determined [18]; 𝐾 = 𝐻𝑐 ×𝑀𝑠 0.96 (11) µ 𝑖 = 𝑀 𝑠 2 ×𝐷 𝐾 (12) It was observed that the minimum magneto crystalline anisotropic constant and maximum initial permeability were observed for GNPs 2.5wt% concentration.…”

Study of the role of dysprosium substitution in tuning structural, optical, electrical, dielectric, ferroelectric, and magnetic properties of bismuth ferrite multiferroic

“…With the inclusion of Dy 3+ ions, the initial permeability was reduced to a minimum of 1.504 for x = 0.45 as compared to doped samples. Microwave frequency was calculated using the relation 𝜔 𝑚 = 8𝜋 2 𝑀 𝑠 𝛾, where γ is a gyromagnetic fraction with the significance of 2.8 MHz/Oe [53][54][55][56][57].…”
