FIG. 1.

(Color online) Transmission electron micrograph for nanocrystalline prepared at (sample S36). Inset: (a) A typical EDX spectrum. (b) A high resolution transmission electron microscopy image of the inside portion of a particle showing lattice-resolved planes.

FIG. 2.

(Color online) Temperature dependence of field cooled susceptibility during cooling and heating cycles for (a) S62 and (b) S36. Samples are field cooled and measurements have been done at magnetic field. Insets: Temperature dependence of resistivity in the absence of magnetic field during cooling and heating cycles. The value of resistivity is normalized to the value at .

FIG. 3.

(Color online) Magnetic field dependence of magnetoresistance at different temperatures (300, 250, 150, 100, and ) for (a) S78, (b) S62, and (c) S36. (d) Comparison between magnetoresistance in low magnetic field region obtained for S78, S62, and S36 at during increasing of field. Magnetoresistance is defined as , where and are resistances in the presence and in the absence of magnetic field, respectively.
