Poster Studies on different properties of LNSMO nanoparticle
The structural, morphological, electrical, magneto-transport properties of manganese based and Nd doped (La1-xNdx)0.7Sr0.3MnO3perovskite with different concentrations are presented. The materials were prepared by the citrateprecursor method of sintering at 1000 °C for 2 hrs. The sample were characterized by X-ray diffraction (XRD), atomic forcemicroscopy (AFM), electrical & magneto-transport measurements. The phase contents a nd lattice parameters were studied byXRD. XRD patterns of the samples indicates that which changes from monoclinic to orthorhombic after doping the particularconcentration of Nd. The crystallite size was calculated by Debye Scherrer’s formula through XRD patterns and got the valuesin 21 – 43 nanometer (nm) for all the samples. The grain size, surface roughness & morphology were studied by atomic forcemicroscopy. Electrical & magneto-transport data were carried out physical property measurement system (PPMS). The electricalresistivity was measured as a function of temperature in different magnetic fields. The insulator-metal transition temperatureshifted to a higher temperature with the application of the magnetic field. The magneto-resistance (MR ) as a function of appliedmagnetic field up to 14 Tesla for above samples which is best effect for colossal magneto-resistance (CMR) materials.
