Abstract:

Perovskite manganites have been the focus of worldwide research during the last two decades because of the observation of colossal magnetoresistance (CMR) effect. These materials have potential applications in magnetic field sensors, spin filters, infrared bolometers and cathodes for solid oxide fuel cells. Such manganites are also important from the fundamental study viewpoint as they offer interplay among various degrees of freedom viz. spin, lattice and charge ordering. Moreover, phase separation may occur in manganites with low concentration of the dopant. In such scenario, ferromagnetic m

Abstract:

The Systematic investigation of structural behaviour of GdMn1-xCrxO3 (x=0, 0.1, 0.2) has been undertaken which are synthesized by conventional solid state reaction method. All the XRD reflection lines were successfully indexed according to orthorhombic perovskite structure with space group: pbnm (62). Upon chromium (Cr) doping on the Mn site the unit cell volume has reduced due to slight difference between the ionic radii of Cr 3+ and Mn 3+ compare with Pure GdMnO 3. The relation between lattice parameter infer that all the samples have O´ type orthorhombic structure which is highly distorted

Abstract:

In this work attempts to prepare strontium-doped lanthanum manganites La1-xSrxMnO3 using microwave-assisted hydrothermal synthesis were undertaken from a mixture of lanthanum nitrate, strontium nitrate, manganese(II) nitrate, potassium permanganate and potassium hydroxide as a mineralizer. For x = 0.3, and x = 0.5, the perovskite obtained is not defined since both La0.7Sr0.3MnO3 and La0.5Sr0.5MnO3 phases are consistent with XRD spectra. While with x = 1.0, for the first time, hexagonal strontium manganite was prepared as blade-shaped crystallites with a narrow particle length distribution (ran

Abstract:

The electronic structure of the perovskite manganites LaMnO3 and La2/3 Al1/3 MnO3 was presented. The calculations were made within density functional theory (DFT) and PBE exchange correlations energy approximation. It was found that inclusion of Al dopants add additional states near the Fermi level and decreasing the resistivity values for all temperature range.

Abstract:

In this work the advantage of the use of the microwave technology was exploited for the preparation of perovskite ceramics. Microwave-assisted hydrothermal method has been applied to the preparation of strontium-doped lanthanum manganites with different stoichiometric ratio of the three oxides, La1-x SrxMnO3 (x = 0.3, 0.5, 0.6). In particular, pure black narrow dispersed crystallites of La0.5Sr0.5MnO3 of 0.68?0.18 ?m were prepared in only 45 minutes at 240?C and a KOH concentration of 21 M. The complete chemical, mineralogical and microstructural characterization of the powders reveal the same
