Heat capacities of several Co2YZ Heusler compounds

• Heat contents from 600 K to 1500 K of selected Co2YZ were measured by drop calorimeters.
• Heat capacities were obtained by taking derivatives of heats contents which were fitted with second order polynomial with respect to temperature.
• Melting points determined by DSC were consistent with literature data.
• Heats of fusion determined by DSC were comparable with those obtained by extrapolation of heat contents.

Heat contents of several Co2-based Heusler compounds Co2YZ (Y = Fe, Mn, Ti; Z = Al, Ga, Si, Ge, Sn) were measured from 500 K to 1500 K using a Setaram MTHC 96 drop calorimeter. Second order polynomials were adopted to fit the data and heat capacities were obtained by taking the derivatives with respect to temperature. Melting points were determined by differential scanning calorimetry (DSC) and measured heats of fusion were compared with those obtained from extrapolation of heat contents.
