“…Such observation can be suggested due to the DE mechanism arised from the ratio of Mn 3+ and Mn 4+ [33]. However, the substitution of Co for x = 0.05 unveiled the paramagnetic-antiferromagnetic transition along the temperature range with TN approximately at 113 K. This can be suggested due to the weakening of DE interaction and superexchange antiferromagnetic interaction takes place down the temperature range [34]. Figure 6 which agreed with previous study [35].…”

This paper reports influences of cobalt (Co) substituted at Mn-site of Pr0.75Na0.25Mn1-xCoxO3 and Nd0.75Na0.25Mn1-yCoyO3 on structure, electrical transport and magnetic properties. All of the samples were prepared via standard solid state reaction method. X-ray diffraction measurement indicates that all samples were crystallized in an orthorhombic structure (space group Pnma). Resistivity measurement displays the x = 0 sample manifests an insulator behavior while metal-insulator transition was found at 108 K and 84 K for x = 0.02 and 0.05 respectively for Pr0.75Na0.25Mn1-xCoxO3. On the other hand, all of the samples for Nd0.75Na0.25Mn1-yCoyO3 showed insulator behavior down to low temperature and analysis of the resistivity change with respect to temperature, dlnρ/dT-1 versus T reveals a slope changes of resistivity have been recorded. Two obvious peaks were recorded from the analysis for y = 0.02 and 0.05 which can be suggested to the existence of charge order transition at the vicinity. For magnetic properties, x = 0 sample showed a paramagnetic-antiferromagnetic transition and further substitution of Co, x = 0.02 and 0.05, induce the paramagnetic-ferromagnetic transition and antiferromagnetic arrangement respectively. Meanwhile, further substitution of Co, y = 0.02 and 0.05 indicate antiferromagnetic transition with increasing TN as Co increased.

“…Theoretical saturation magnetization value (l th ) for these compositions can be calculated using the relation, 27 l th ¼ ðð0:7Þ Â 4l B Þ þ ðð0:3 À xÞ Â 3 l B Þ, which comes out to be 3.25l B , and 3.55l B for LCMO15 and LCMO5, respectively. The saturation magnetization value for the LCMO calculated using the same relation is 3.7l B .…”

“…Earlier studies on manganites predicted the field dependent behavior of MR in terms of the polaron conduction. [27][28][29] It was suggested that MR above T c is quadratic in the magnetic field over a broad range while below T c , MR shows linear dependence at moderate magnetic field values. Also, in the vicinity of T c , MR curve follows the exponential behavior.…”

In this work, we present a systematic study on the effect of monovalent and divalent cation inclusion on the magnetic properties of the manganites series La0.80(Ag1−xSrx)0.20MnO3 (x = 0.0–1.0) synthesized by the solid‐state reaction method. The decreasing Sr:Ag proportion across the compositional series was verified by X‐ray photoelectron spectroscopy. Concerning magnetic properties, the hysteresis curves manifested an initial paramagnetic response at x = 0.0, followed by a progressive ferromagnetic behavior with an optimum Ag:Sr ratio at x = 0.75, for which an enhanced saturation magnetization of 51 Am2/kg and a Curie temperature of 336 K were recorded. Results are explained on the basis of the effect of the increasing unit cell volume on the double exchange interaction between magnetic Mn3+– Mn4+ atoms.
