“…The TC was determined using Figure 6 shows the temperature dependence of the AC susceptibility of the Nd 1−x Bi x MnO 3 system on the real part χ' with the inset dχ'/dT versus the temperature range of 30-300 K. For x = 0 and x = 0.25, a definite and sharp peak was observed at 70 K and 72 K, respectively, associated to the ordering temperature of Mn spins [22]. The observed cusp depicts the PM to AFM transition, which is consistent with the results from previous studies [5,8,23]. For x = 0.50, two sharp peaks were observed, which were at 42 K and 57 K, respectively.…”

“…Primarily, undoped NdMnO 3 is an antiferromagnetic (AFM) insulator with Néel temperature 67.2 K due to the interplay between the ferromagnetic (FM) DE and AFM SE interactions present in the compound [5]. Chatterji et al confirmed that NdMnO 3 has an A-type AFM structure of the Mn magnetic sublattice below Néel temperature, T N ≈ 81.7 K [6].…”

“…In this case, both authors suggested that the presence of CO was due to the JT distortion, resulting in the distortion of MnO 6 octahedral and localization of charge carrier, by decreasing its mobility, which seemed to weaken the DE interaction [7][8][9]. Meanwhile, when NdMnO 3 was doped with monovalent cations such as Na + and K + , it showed an FM insulator behavior and CO transition was observed for Nd 1−x Na x MnO 3 at −250 K when x > 0.1 [5,10]. However, a lack of knowledge still exists on Nd series doped with trivalent cations such as Nd 1−x Bi x MnO 3 .…”

This study synthesizes the neodymium-based manganites with Bi doping, Nd1−xBixMnO3 (x = 0, 0.25 and 0.50) using the solid-state reaction route. The crystal structural, morphological and magnetic properties were determined using X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) and AC magnetic susceptibility. The Rietveld refinement confirmed that the compounds were in the single-phase orthorhombic structure of the NdMnO3 with Pbnm space group and lattice parameter b increased with doping from 5.5571 (x = 0) to 5.6787 (x = 0.5). FTIR spectra showed that absorption bands were located within the range of 550–600 cm−1, which corresponded to the Mn–O stretching vibration. FESEM exhibited homogenous compound. The AC magnetic susceptibility measurement studies showed a strong antiferromagnetic (AFM) to paramagnetic (PM) transition existed at 76 K, 77 K and 67 K for samples (x = 0, 0.25 and 0.50), respectively.

“…The Rietveld software MAUD (version 2.26) [16,17] has been used in our study to refine the microstructural parameters through a least square method. The pseudo-Voigt (pV) function is used to fit experimental profile as it takes care of both the particle size and strain broadening of the experimental data.…”

We have investigated the structure and magnetic properties of the Nd0.88MnO3 (NMO) perovskite thin-film layers by liquid-injection MOCVD tried on SrTiO3 (STO) (100) substrates. The structural examinations showed that the growing film was amorphous. It changed to the crystalline phase after being annealed at 900 ºC in the air for 24 h. A minor secondary phase identified as Mn3O4 appears. The film is subjected to in-plane (IP) tensile stress leading to a contraction of the film out of the plane (OOP) lattice parameters. The orientation relationships for the film structure is described near the interface as [101 ̅ ]NMO//[100]STO and [010]NMO//[001]STO. The NMO thin film showed ferromagnetic ordering with a transition temperature TC =85K. The large bifurcation between ZFC and FC curves with a cusp at Tf = 53 K; and an irreversible temperature Tirr= 48 Kproves the spin-glass behavior with long-range ferromagnetic order (Mn 3+ -O 2--Mn 4+ ) coexists in NMO thin films. The magnetic easy axis corresponded to the surface normal.
