FIG. 4.

Activation energy as obtained from Eq. (1) for all samples at and 0.8 T. The glass transition temperature is obtained when crosses the solid line .

Image of FIG. 5.
FIG. 5.

The log-log plot of normalized resistivity vs scaled temperature for the sample H100 at 0.4 and 0.8 T. The slope of the curve (lower temperature region marked by a straight line) gives the critical exponent, .
