在0.3 - 20 K之间测量了金属相和绝缘相SmS的热容。在金属相中测量了3 - 298 K之间的电阻率，并在4.2 - 473 K下测量了电阻率随压力的变化。熵差清楚地显示了金属相中4f电子的退磁。在金属相中，电阻率随着温度的降低而增加。金属SmS的热容量和电阻率与Sm B 6的热容量和电阻率非常相似，这表明相同的潜在机制是这两种物质的不寻常性质的原因。
The heat capacity of SmS has been measured in the metallic and insulating phases between 0.3 and 20 K. The electrical resistivity has been measured between 3 and 298 K in the metallic phase and as a function of pressure at 4.2 and 473 K. The entropy difference shows clearly the demagnetization of the 4 f electrons in the metallic phase. The electrical resistivity increases with decreasing temperature in the metallic phase. The heat capacity and resistivity of metallic SmS are very similar to those of Sm B 6, suggesting that the same underlying mechanism is responsible for the unusual properties of both substances.
