The measurement of resistivity and longitudinal magnetoresistance is reported in amorphous Fe76-xNi,Cr4B12Sis (0 < x < 20) alloys. The presence of Ni shows a significant effect on the high temperature minimum observed in aFe-Cr-B-Si alloys. Also it is found that with addition of Ni, magnetoresistance seems to become temperature dependent.
CeCu6-,Au, and CeCu6-,Ag, alloys order antiferromagnetically (e.g. TN = 0.95 K for the Au alloy with x = 0.5) as seen in the specific heat, ac susceptibility, and eledrical resistivity. The difference to CeCus, which shows neither magnetic order nor superconductivity, might be due to the negative lattice pressure of Au and Ag or to weakening of the(More)
Noise removal and lesser computational run time of the digital holographic numerical reconstruction procedure are the critical issues for effective and efficient identification of three-dimensional (3D) particle fields. The present study suggests an improved reconstruction procedure based on the superposition principle. The effectiveness of this proposed(More)
