Rare earth compound shows a variety of strongly correlated behaviors, which attract our interests. PrOs4Sb12 exhibit unconventional superconductivity when the temperature is lower than 1.85K and NdOs4Sb12 display ferromagnetism below 0.9K. We want to understand how the Nd doping affects the PrOs4Sb12. In order to figure out the properties of the material, we decide to evaluate Pr1-xNdxOs4Sb12 heat capacity varying with the temperature. The specific heat of filled skutterudites Pr1-xNdxOs4Sb12 has been measured with different Nd concentrations: x= 0.10, 0.25, 0.30, 0.45, 0.50, 0.55, 0.60, 0.75, 0.80, and 1.00 from 10K to 300K. The specific heat data was analyzed by a combination of the Debye, Einstein, and Sommerfeld models, which tell us the information of Debye temperature, Einstein temperature, and electronic specific heat coefficient respectively. In turn, these parameters refer to the stiffness of the crystalline lattice, rattling effect, and electron correlation of each sample. The value acts as a guide to determine the behaviors of this substitution system.
