Abstract

In this study we report on the transport properties of the Ti-based ternary carbide (formula presented) The Hall effect and longitudinal magnetoresistance have been measured as a function of temperature in the 4-300 K range and at magnetic fields up to 5 T. The magnetoresistance is dominated by a positive quadratic field dependence at low temperatures. The Hall voltage is a linear function of magnetic field over the range of temperatures investigated. The effective carrier concentration and mobilities were calculated based on the sign and value of the Hall coefficient. These results are discussed in terms of a two-band model and compared to the single-band approximation. The magnetic susceptibility (formula presented) was found to be independent of temperature and field. These results were used to evaluate the charge concentration in light of Pauli paramaganetism theory.
