“…We have found that there is an anomalous decrease below 55.3 K in the specific magnetization (σ) as a function of test temperature (T ) when x≤0.15, which is similar to observations reported by Boujelben et al 17 Analyzing the experimental results using the O2p itinerant electron model, we have explained the magnetic structure.…”

“…For the temperature T CP shown in Fig. 4 (c), there are disagreements in previous reports [15][16][17][18] regarding the magnetic moment directions of the Pr and Mn cations in the samples. In what follows, we address these questions using the O2p itinerant electron model.…”

“…Boujelben et al 17 also found that the average moments of Mn and Pr cations were 3.47 and -0.11 µ B , respectively, using neutron diffraction analysis. These experimental results indicate that there are cant angles between the magnetic moments of the Mn cations in the B sublattice and between the Pr cations in the A sublattice.…”

“…However, Jirák et al 16 prepared a polycrystalline sample of Pr 0.6 Ca 0.4 MnO 3 , and claimed that the magnetic moment direction of the Pr 3+ cations was parallel to that of the Mn cations. Boujelben et al 17 likewise prepared Pr 0.6 Sr 0.4 MnO 3 powder using a solid state reaction method, but considered that the magnetic moment direction of the Pr 3+ cations was antiparallel to that of the Mn cations. Fauth et al 18 investigated Nd 0.7 Ba 0.3 MnO 3 and they concluded, on the basis of neutron powder diffraction experiments, that there was an antiparallel ordering for the Mn and Nd cations.…”

Powder samples of the ABO3 perovskite manganites Pr0.6Sr0.4CrxMn1-xO3 (0.00≤x≤0.30) were synthesized using the sol-gel method. X-ray diffraction analyses showed that all the samples had a single-phase orthorhombic structure. By analyzing magnetic parameters on the basis of the O2p itinerant electron model, we found that there are two magnetic transition temperatures, TCM and TCP, corresponding to changes in the magnetic ordering for the Mn and Pr cations, respectively. The magnetic moments of Mn3+ and Cr3+ cations within the B sublattice show canted ferromagnetic coupling, and the magnetic moments of the Pr cations within the A sublattice also show canted ferromagnetic coupling. However, the total magnetic moment of the A sublattice shows antiferromagnetic coupling against that of the B sublattice. The assumption of the canted ferromagnetic coupling within the B sublattice was confirmed using magnetoresistance experimental results.

“…55 Mn nuclear magnetic resonance (NMR) measurements showed a single resonance peak at a frequency corresponding to an average value of the Mn 4+ and Mn 3+ resonance frequencies. This result rules out the possibility of short-range charge order and confirms a homogeneous metallic state [10]. Here, we investigate the nature of the FM transition in Pr 0.6 Sr 0.4 MnO 3 single crystals by measuring a series of magnetization isotherms encompassing the Curie temperature T C .…”

We report on the magnetic and electrical properties of Pr 0.6 Sr 0.4 MnO 3 single crystals. This compound undergoes a continuous paramagnetic-ferromagnetic transition with a Curie temperature T C ∼ 301 K and a first-order structural transition at T S ∼ 64 K. At T S , the magnetic susceptibility exhibits an abrupt jump, and a corresponding small hump is seen in the resistivity. The critical behavior of the static magnetization and the temperature dependence of the resistivity are consistent with the behavior expected for a nearly isotropic ferromagnet with short-range exchange belonging to the Heisenberg universality class. The magnetization (M-H ) curves below T S are anomalous in that the virgin curve lies outside the subsequent M-H loops. The hysteretic structural transition at T S as well as the irreversible magnetization processes below T S can be explained by phase separation between a high-temperature orthorhombic and a low-temperature monoclinic ferromagnetic phase.
