摘要：
La content dependence of superconducting critical temperature (T-C) of LaxRh4P12 was investigated. The samples were synthesized using a belt-type high-pressure apparatus at pressures of 5.5 and 7.7 GPa, and temperatures of 1373 and 1473 K. The La content (x), the lattice parameter and T-C increase when the synthesis pressure is increased. These results suggest that both the lattice parameter and T-C increase with x, when x is in the range 0.70 to 0.85.
