Abstract

The specific heat of single-crystalline superconducting SmBa2Cu3O7−x has been measured in the temperature range 0.3–7 K in magnetic fields between 0 and 8 T applied parallel and perpendicular to the c-direction. A broad Schottky-type anomaly with maximum at 0.99 K was observed. The anomaly is very weakly magnetic field dependent. The applied field of 8 T along c-direction shift the anomaly up to 1.24 K, whereas almost no influence on the position of the peak was observed with applying field perpendicular to the c-direction. However, in both cases the anomaly was slightly lowered and broadened.
