A NOTE ON THE NEGATIVE TEMPERATURE COEFFICIENT OF RESISTIVITY OF A Fe-25Mn-5Al-0.2C ALLOY IN LOW TEMPERATURE
Fe-25Mn—5Al-0.2C合金低温电阻率的负温度系数行为

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.
