“…A wide range of studies has been conducted, focusing on various methods and chemicals [9] for improving the magnetic, electrical, and dielectric properties of these materials, which may be potential candidates for industrial applications such as spintronic-based devices [4,5,10], magnetic sensors [4], non-volatile memory elements [10], and supercapacitor electrodes. Thus, the tuneable properties exhibited by manganites make them highly attractive candidates for utilisation in various applications which also depending on few factors such as temperature and doping used in the investigation [9,11].…”

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.
