| 摘 要： | 在4.2K到300K之间,在大块晶态Fe-25Mn-5Al-0.2C合金中观察到了反常的电阻负温度系数行为,在50K以下,电阻率大体和lnT成正比,可能起源于磁性的机制。

| Abstract: | An anomalous behaviour of the negative temperature coefficient of resistivity of a crystalline bulk Fe-25Mn-5Al-0.2C alloy was observed at low temperatures. Below 50 K the resistivity is roughly proportional to InT. It seems that the anomaly is due to some land of magnetical mechanism. |
