ELECTRICAL RESISTIVITY, HALL EFFECT AND SUPERCONDUCTIVITY OF SOME b.c.c. TITANIUM-MOLYBDENUM ALLOYS
The electrical resistivities and the Hall coefficients of a series of body centered cubic Ti--Mo alloys have been measured between 1.1 deg K and room temperature, in magnetic fields up to 30 kgauss, and for concentrations of Mo between 7 and 24 at%. For the lower Mo concentration alloys the resistivities are high ( approx equal 140 microhm cm), and are slightly larger at 4.2 than at 300 deg K. The resistivities decrease with increase of Mo over the entire range of alloy concentrations studied. The Hall coefficients are positive and are appreciably concentration and temperature dependent only below solute concentrations of about 12 at% Mo. The alloys are all superconducting at liquid helium temperatures, their resistive superconducting transition temperatures increasing with increase of Mo. Atomic ordering and structural transformation, concentration and temperature dependent electronic factors, and spin-disorder scattering are considered as possible explanations for the anomalous concentration and temperatare dependence of the resistivity.
