ac photopyroelectric calorimeters in the standard back configuration, where LiTaO₃ is one of the most popular materials to be used as a detector, are commonly used to study phase transitions in solids and liquids. In order to extract the specific heat of a studied sample, a good knowledge of the thermal effusivity of the sensor as a function of temperature is needed. This function has been obtained for the first time in the range 15 K to 400 K by independently measuring LiTaO₃ thermal diffusivity and specific heat and combining both of them to give thermal effusivity. Using this photopyroelectric setup and LiTaO₃ as sensor, we have carried out the study of the critical behavior of the antiferromagnetic ordering of the Eu²⁺ spins in EuCo₂As₂ (a compound with similar structure as EuFe₂As₂, from which superconductors have been developed) at low temperature by measuring its specific heat. Furthermore, the critical parameters found for EuCo₂As₂ (α=–0.017,A⁺/A^–=1.06) agree with the 3D-XY universality class, indicating that the spins present an in-plane arrangement for Eu²⁺, in agreement with magnetic measurements in the literature.
