Pressure induced change in the electronic state of Ta${}_4$Pd${}_3$Te${}_{16}$

Abstract

We present measurements of superconducting transition temperature, resistivity, magnetoresistivity and temperature dependence of the upper critical field of Ta${}_4$Pd${}_3$Te${}_{16}$ under pressures up to 16.4 kbar. All measured properties have an anomaly at $\sim 2-4$ kbar pressure range, in particular there is a maximum in $T_c$ and upper critical field, $H_{c2}(0)$, and minimum in low temperature, normal state resistivity. Qualitatively, the data can be explained considering the density of state at the Fermi level as a dominant parameter.
