Magnetoresistance of selected Sn- and Pb-based solders at 4.2 K

摘要

In this paper, data on the transverse electrical magnetoresistance of various solders at 4.2 K is presented and discussed. The selected solders are frequently used in cryogenic applications; however, their low temperature properties are often unknown. These data were taken at liquid helium temperature (4.2 K) in fields up to 15 T. The discussion of the data is based on the electrical resistivity and magnetoresistance of the pure metals that constitute the major components of the solders, the resistance ratio of the specimens, as well as the composition and the microstructure of the solders. Moreover, the data is presented such that information can be obtained for fields and temperatures other than those investigated here.
