and 1) have been fabricated by co-precipitation strategy. XRD plots emphasized the complete emersion of the solitary-phase Nano-spinel for all the investigated Nano-powders. Nano-powders crystallite size R declined with x. FTIR emphasized the emersion of Nano-spinel phase. DTA/TGA showed decline in samples' weight giving largest weight loss ≈ 22 %. Cycle voltammetry and charging/discharging inspection were done to scrutinize the electrochemical merits of MnLa0.12Fe1.88O4 spinels in 1 M KOH electrolytic soln. MnLa0.12Fe1.88O4 Nano-spinels possess specified capacitance of 1500 mF/g at 50 mV/s. The scrutiny illustrates a promising implementation of MnLa0.12Fe1.88O4 Nano-spinels as electrode nanocrystals for energy storage and sensing. Nyquist diagrams of MnLa0.12Fe1.88O4 Nano-spinels in frequency range appeared from 1.0 Hz to 20 kHz. MnLa0.12Fe1.88O4 Nano-spinels retain low soln reluctance (Rs) as 12.9 Ω.

“…A very small portion of the sample would not have interacted with electromagnetic radiation. The average crystallite size ( D ) of powder samples is evaluated using Debye–Scherrer formula and it is gradually increasing with zinc substitution. This kind of behavior is achieved due to decrease in elastic strain (ε) with increase in x (Table ).…”

Magnesium is replaced systematically by zinc in Ni0.2Mg0.8‐xZnxFe2O4 (x = 0.2–0.8) prepared by microwave‐assisted solid‐state reaction route. The structure is confirmed by X‐ray diffractograms. An improvement in initial permeability is observed with substituent in Ni0.2Mg0.8‐xZnxFe2O4 due to increase in average grain size. The obtained permeability values are varying between 106 and 687 at 1 MHz. The permeability plots revealed that Curie‐transition temperature (Tc) is decreasing with increase in zinc. Both x = 0.2 and 0.4 compositions show low relative loss factor of order 10−5 to 10−4, which are exhibiting required magnetic properties for transformer and inductor core applications.
