Thermal conductivity of some dilute silver alloys at low temperatures and in magnetic fields

Synopsis Results of investigations on thermal conductivity of dilute AgMn alloys and of a dilute AgIn alloy are given. It is anomalous that a magnetic field causes an increase in the conductivity of alloys containing manganese at liquid helium temperatures, amounting even to .26% in fields of 25 kOe for the alloy with 0.14 at.% Mn.

89. Measurements on the magnetic susceptibilities of AgMn and CuMn alloys

Measurements have been carried out on alloys of Ag-Mn and Cu-Mn with different concentrations of manganese between room temperature and liquid hydrogen temperatures. A paramagnetic behaviour has been found. We examined especially the dependence of the susceptibilities on the field strength; no field dependence could be detected except in some of the Ag-Mn alloys, but this effect originated from small ferromagnetic impurities which were determined by means of the method of Honda. The concentration of the maganese has been determined magnetically and compared with determinations based on the electrical resistance.
