Magnetic Susceptibility and Electrical Resistivity of Dilute Chromium–Titanium Alloys

We report measurements of the magnetic susceptibility and the electrical resistivity of chromium–titanium alloys containing Ti concentrations of up to 0.6 at.%. The measurements were performed between 320 and 4.2 K. A very rapid depression of both the Néel temperature and the spin-flip temperature on alloying was observed. The paramagnetic susceptibility of pure chromium and the alloys displayed a linear temperature dependence and it is suggested that thermal expansion effects might be responsible for this linear temperature dependence. The analysis of the electrical resistivity results points to the existence of an extra electron scattering mechanism above TN in pure chromium as well as the dilute alloys.
