Abstract

Resistivity, thermoelectric power, heat capacity, and magnetization for samples of Ru Sr2 (Gd1.5 Ce0.5) Cu2 O10-δ were investigated in the temperature range 1.8-300 K with a magnetic field up to 8 T. The resistive transitions to the superconducting state are found to be determined by the inhomogeneous (granular) structure, characterized by the intragranular, Tc0, and intergranular, Tcg, transition temperatures. Heat capacity, C (T), shows a jump at the superconducting transition temperature Tc0 ≈37.5 K. A Schottky-type anomaly is found in C (T) below 20 K. This low-temperature anomaly can be attributed to splitting of the ground term S 72 8 of paramagnetic Gd3+ ions by internal and external magnetic fields.
