“…All diffraction peaks were indexed in an orthorhombic perovskite structure with the space group pmna (No.62) as shown in Figure 1 (b). This result aligns with the published data for the undoped sample [2,20] which indicated a good quality data. The structural parameters from the Rietveld refinement for Pr 0.75 Na 0.05 K 0.20 Mn 0.95 Fe 0.05 O 3 manganite are listed in Table 1.…”

“…As previously reported, the Pr 0.75 Na 0.05 K 0.2 MnO 3 compound exhibited a metal insulator (M-I) transition at transition temperature (T MI ) of 122 K for 0 T and 0.8 T of applied field [20]. In contrast, substitution of Fe in Pr 0.75 Na 0.05 K 0.20 Mn 0.95 Fe 0.05 O 3 sample exhibits insulating behavior over the whole temperature range from 30 K to 300 K for 0 T field.…”

“…The structural parameters from the Rietveld refinement for Pr 0.75 Na 0.05 K 0.20 Mn 0.95 Fe 0.05 O 3 manganite are listed in Table 1. The tolerance factor (τ) was measured to determine the stability of the structure was discovered to have a similar value (0.9451) to the parent compound of Pr 0.75 Na 0.05 K 0.20 MnO 3 as stated by previously published data [20]. The results showed that the Fe substitution at Mn-site had no effect on the structure of the investigated sample could be due to similar ionic radius of Fe 3+ and Mn 3+ ions (0.645 Ǻ) [21,22].…”

“…5.4337 (2) χ 2 1.272 𝜏𝜏𝜏𝜏 0.9451 [20], the parent compound has a higher T C value (140.7 K) compared to the studied sample [20]. The significant decrease in T C could be attributed to a weakening of ferromagnetic (FM) interaction caused by an enhancement of antiferromagnetic (AFM) ordering with Fe substitution [3].…”

The effects of partial substitution of Fe at the Mn site on structural, magnetic, and electrical properties of monovalent doped Pr0.75Na0.05K0.20Mn0.95Fe0.05O3 manganite prepared by the solid-state method were investigated. X-ray Diffractometer, AC Susceptibility, and four point probe measurements were used to characterize the structural, magnetic, and electrical properties. The sample crystallized in an orthorhombic structure with a Pnma space group. The sample exhibited ferromagnetic (FM) to paramagnetic (PM) transition behaviour with Curie Temperature, TC value of 121.5 K. From the Resistivity versus temperature analysis, the sample exhibited insulating behaviourover entire temperature from 30 K - 300 K. Fe substitution exhibited high magnetoresistance (MR %) value at low temperature region, indicating the extrinsic mechanism of MR effect.

In this paper, we discuss the structural and morphology properties of the solid-state prepared Pr0.67Ba0.33MnO3 perovskite manganite X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analyses were utilised to examine the structure, morphology, and chemical composition. The compound exhibits a single phase with an orthorhombic perovskite structure with a Pnma space group without any impurities. The refined cell parameters are a = 5.504 Å, b = 7.778 Å, and c = 5.528 Å (α = β = γ = 90° and a ≠ b ≠ c), therefore the cell volume is 236.723 Å^3. The tolerance factor is used to predict the stability of the Pr0.67Ba0.33MnO3, which is τ = 0.9241. Fourier transform infrared spectroscopy (FTIR) reveals that the Mn-O bonds appear at 600 cm^(-1). In addition, morphology SEM revealed that the grain sizes are heterogeneous, and the grain shapes are irregular. Using EDX technique, the percentage elemental composition of Pr, Ba, Mn, and O was determined. The values of the atomic percentages for each element are almost identical to the ratios of the elements during sample preparation.
