Structural and magnetic properties of nanoparticles of La2/3Sr1/3MnO3

Nanoparticles of the manganite were synthesized using the Pechini process and their structural properties were characterized by X-ray diffraction (XRD) and by transmission electron microscopy (TEM). The magnetization of compacted powders was measured for temperatures in the range . The estimated av...
