Magnetic susceptibility of Bi2Te3-Sb2Te3 alloys

Melting and solidification of bismuth antimony telluride under a high magnetic field: A new route to high thermoelectric performance

“…Obviously, the endothermic peak in the melting curves ( Fig.1a) is nearly unaffected by the magnetic field, with an extreme at about 883.5K, and the extrapolated onset temperature (T M ) is about 870.8K for all the samples, indicating that the solid melting phase transformation can hardly be affected by the given magnetic field. It should mainly be attributed to the low magnetic energy, estimated to be the order of 10 -4 J/g when considering the maximum magnetic field (6T) and taking the magnetic susceptibilities of BST as 0.3×10 -6 cm 3 /g [15], which is negligible compared with the specific heat of this compound. The exothermic peak in the DTA curves in Fig.…”
