摘要

La_(0.5)Sr_(0.5)Ti_(1-x)FexO_3 (x = 0,0.05 and 0.1) nanopowders was prepared by hydrothermal method in 2 M KOH solution at 220 ℃ for 24 h. The structure and morphology of the products were characterized by X-ray diffraction, field emission scanning electron microscope and transmission electron microscope. Magnetic properties were measured at room temperature using a vibrating sample magnetometer. All product powder showed the single phase of La_(0.5)Sr_(0.5)Ti_(1-x)FexO_3 cubic structure without any impurity phase. The product powders consist of the cubic, plate-like and irregular particles with particles sizes in the range of 48-92,75-149 and 25-75 nm, respectively. The undoped La_(0.5)Sr_(0.5)TiO_3 sample exhibits diamag-netic behavior, whereas the Fe-doped La_(0.5)Sr_(0.5)TiO_3 samples are ferromagnetic having the saturation magnetizations of 0.00085-0.016 emu/g.
