It may have been due to unidentified impurities, or more likely an instrument connection problem-only one test on one sample was done ), In fact, in engineering, we usually take the resistivity curve above the Curie point as a straight line.
2.
:: : : In the case of iron ( Fe ), a phase change occurs at 1183 K ( from body centred to face centred ), but the Curie point is below this at 1043 K . The resistivity curve follows Worthing's formula accurately ( better than +,-1 % ) with P = 1.768 up to the Curie point then continues with P close to unity up to and past 1183 K . There may be an inflection point at 1183 K but it is difficult to detect in measured data . ( A paper by V E Zinovev & others in the Soviet Journal of Physics in 1972 claimed a slight step at about 1200 K but to my knowlege this hasn't been replicated.
