Research output: Contribution to journalArticlepeer-review


Duplex structure alloys consisting of insoluble metallic particles finely and homogeneously embedded in cubic Ge or amorphous AlxOy matrix were prepared by a rapid quenching of the insoluble type alloys of Ge-M and AlxOy-M (M=Pb, Bi, Sn and In). The duplex alloys were found to exhibit an anomalously high field superconductivity, probably because of the unique dispersed structures which cannot be obtained by the conventional preparation process. The anomalous superconductivity is stated to be a kind of hybrid properties which has so far not been observed for conventional single-phase alloys and composite alloys.
