Abstract
WHEN a paramagnetic substance, which follows Curie's law, is subjected to an alternating magnetic field, a certain amount of heat has been found to be developed per second in the substance. At room temperature only a very feeble effect could be observed for various paramagnetic substances. But at low temperatures, on account of the increased susceptibilities and the decreased specific heats, better conditions for the study of this phenomenon might be expected. Prof. W. J. de Haas kindly put the facilities of the Kamerlingh Onnes Laboratory at my disposal. The effect proved to be very large indeed at low temperatures. At 14°, for example, in a field of amplitude 8 gauss and frequency 2 × 107, the increase in temperature of the calorimeter filled with ferric alum amounted to 0.04° per second.
