Thomson effect of Nitrogen






A. Battelli, and A. W. Foster studied the Thomson effect. H. E. Smith found that the Thomson effect decreases with tension by becoming less negative, until the elastic limit is reached, after which it increases. P. W. Bridgman found for the J'homson effect, cr, of nickel and lead, σ×106 = -0.0356(θ+273) volts per degree; and for uncompressed nickel against nickel compressed at a press., p, the Thomson effect, σ×108 joules per coulomb per degree, is:

20°40°60°80°100°
20004.42.12.213.86.08.6
60008.67.47.27.27.37.5
1200016.416.516.214.612.29.6


H. E. Smith studied the effect of strain on the Thomson effect. J. Dorfman and co-workers found that the curves for the thermoelectric force of nickel against platinum show a break in the neighbourhood of the Curie point. This corresponds with a more or less rapid change in the Thomson effect - the sp. ht. of electricity. E. C. Stoner studied the problem on the assumption that ferromagnetism is due to electronic spin, and he calculated the sp. ht. per electron to be 3 cals. per gram electron - J. Dorfman and co-workers found 2.88 cals.
