Magnetic dynamics of charge ordered Nd0.80Na0.20MnO3 compound

Effect of sodium doping on the microstructure, lattice distortion and magnetic properties of GdMnO3 tiny single crystals

“…This large bifurcation is a signature of magnetic anisotropy in the compound arising from competing weak ferromagnetic and anti-ferromagnetic behavior and presence of spin glass like phase. 35,47 Structural anisotropy also may be a reason of magnetic anisotropy. This gure also shows that ICAFM and c-AFM regions are divided by a peak.…”

Effects of monovalent cation doping on the structure, microstructure, lattice distortion and magnetic behavior of single crystalline NdMnO3compounds

“…15 However, the in depth structural characterization and study of the monovalent cation doping effect on octahedral distortion were not addressed previously. [24][25][26][27][28] NdMnO 3 shows a paramagnetic to antiferromagnetic phase transition with Neel temperature at 67 K. 29 On the other hand, both 15 mol% Na-and K-doped NdMnO 3 compounds show paramagnetic to ferromagnetic phase transitions with a Curie temperature at ∼100 K. [25][26][27][28][29] In this article emphasis is given on the following aspects: (i) detailed crystal structures, microstructures and lattice distortions in these three compounds due to monovalent doping, (ii) the effect of sintering temperature on the formation of these compounds and (iii) temperature dependent magnetization to elucidate the effect of monovalent doping on the magnetic properties of NdMnO 3 .…”
