The specific heat of nickel and of some nickel-copper alloys
The study of the alloys of the ferromagnetic with other elements promises to elucidate some of the problems of ferromagnetism. Sadron, for instance, has determined the "ferromagnetic moment" of certain foreign elements in nickel. He finds that elements in the same column of the periodic table have nearly the same moment, and that in passing across the table the value of this moment first increases and then decreases. Stoner has recently suggested an interesting interpretation of these results in considering the moments of ferromagnetics in general. The variation of the specific heat with temperature in such binary alloys apparently has not yet been investigated, although the specific heat of the ferromagnetics in the pure state has been the subject of several investigations.
