dc.description.abstractThe substitution of Ga in Ce75Al25-xGax (x = 0 and 4 at.%) metallic glasses (MGs) has led to phase separation giving rise to nano-amorphous domains in a glassy matrix. The CeL3-edge XAS spectra for x = 4 has shown appearance of 4f0 delocalized states. The temperature coefficient of resistance (TCR) becomes higher with addition of Ga. The magnetic field tuned magnetoresistance (MR) transition from positive to negative values has been observed for the first time with Ga substitution. These changes in the transport properties have been discussed in terms of formation of nano-amorphous domains and its link with 4f electrons for Ce atoms. © 2016 Elsevier Ltd. All rights reserved.
