Abstract
The calorimetric and thermopower measurements on Dy5Ge2Si2 are presented. The antiferromagnetic ordering resulted in a sharp peak in specific heat and paramagnetic temperature as a shoulder. Magnetic entropy (Smag) is estimated from the magnetic heat capacity, Cmag and is in good agreement with the theoretically calculated value. A small note on correct assessment of Smag is presented. Thermoelectric power is analysed in line with the specific heat and a temperature region of magnetic correlations is identified. Charge carrier density n~2.5x1023 cm−3 is calculated using Sommerfeld parameter γ and diffusion thermopower constant σD.
