The temperature dependence of the normalized resistivity at the magnetic fields of 0.4 and 0.8 T. The studied glass scaling region is marked by dashed lines.
(a) Plot of vs ( value is shown by an arrow) and (b) plot of vs (slope is determined from the linear portion closer to ) at the magnetic field for H100.
Variation in , , and values as a function of Ho content.
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 .
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, .
