“…Introducing Ru at the Mn site will cause a distortion in the MnO 6 octahedron. Consequently, the Mn-O-Mn bond angle and the Mn-O and Ru-O bond lengths increase (Table 3) [21][22][23]. Bond valence sum (BVS) calculations were performed for Pr 0.67 Ba 0.33 MnO 3 and Pr 0.67 Ba 0.33 Mn 0.9 Ru 0.1 O 3 .…”

This study reports the structural, morphological, and magnetic properties of ruthenium doping at the manganese site in Pr0.67Ba0.33MnO3 manganites. Rietveld refinement X-ray powder diffraction (XRD) data show that Pr0.67Ba0.33MnO3 and Pr0.67Ba0.33Mn0.9Ru0.1O3 crystallize in an orthorhombic perovskite structure with the Pnma space group. Doping with Ru yields an increment in the lattice parameter and unit cell volume. In addition, small changes in the Mn–O–Mn bond angle and bond distance are observed. Field emission scanning electron microscopy (FESEM) is used to examine the surface morphology of the samples. Fourier transform infrared spectroscopy (FTIR) reveals that the Mn–O and metal–oxygen bonds appear at the 600 and 900 cm−1 bands, respectively. The AC magnetic susceptibility measurement studies confirm that a paramagnetic (PM) to ferromagnetic (FM) transition exists at 130 and 153 K for the Pr0.67Ba0.33MnO3 and Pr0.67Ba0.33Mn0.9Ru0.1O3 samples, respectively.

“…The substitution of the transition metal at Mn sites disrupts the Mn 3+ -O 2--Mn 4+ chain leading to the alternation of the Mn 3+ /Mn 4+ ratio. Previous research has investigated doping with other transition metals including Cu, Fe, Ni, Co, and Ru at the Mn site in the LSMO system 11,[18][19][20][21][22][23][24] . Substitution at the Mn-site with transition metals has been reported to have a significant effect on the magnetic and transport behavior of LSMO 18 .…”

This paper investigates the effect of Fe substitution on the structural, magnetic and transport properties of the La0.7Sr0.3MnxFe1-xO3 (LSMO) system where x ranged between 0 and 0.15. Samples were prepared using a non-aqueous sol-gel synthesis method. Structural and chemical analysis confirmed the Fe 3+ substitution at Mn 3+ sites without any impurity phase resulted in a small change in structural parameters of the LSMO. The change in magnetic behavior and Curie temperature of the Fe-doped LSMO is explained through competitive exchange interactions developed in the system. The temperature-dependent resistivity demonstrated that the resistivity of the samples increased with Fe concentration due to different conduction mechanisms related to the ferromagnetic-metallic and paramagnetic-insulating regions. The magneto-transport measurement showed significant improvement in the magnetoresistance due to Fe doping at Mn site, which was attributed to enhancement of the spin-glass phase in Fe doped LSMO system. The reduction in magnetoresistance for higher Fe concentration is explained with the help of percolation threshold mechanism.
