Specific heat of K0.71Na0.29Fe2As2 at very low temperatures
A commercially available calorimeter has been used to investigate the specific heat of a high-quality K0.71Na0.29Fe2As2single crystal. The addenda heat capacity of the calorimeter is determined in the temperature range 0.02K ≤ T ≤. 0.54K. The data of the K0.71Na0.29Fe2As2 crystal imply the presence...

| Zusammenfassung: | A commercially available calorimeter has been used to investigate the specific heat of a high-quality K0.71Na0.29Fe2As2single crystal. The addenda heat capacity of the calorimeter is determined in the temperature range 0.02K ≤ T ≤. 0.54K. The data of the K0.71Na0.29Fe2As2 crystal imply the presence of a large T2 contribution to the specific heat which gives evidence of d-wave order parameter symmetry in the superconducting state. To improve the measurements, a novel design for a calorimeter with a paramagnetic temperature sensor is presented. |
