        In the Curie point of a Ni wire under tension agreement with the Heisenberg theory of ferromagnetism is found.  There is agreement between the curves of temperature against temperature coefficient of resistance and against extension, and there also is similarity with the curve obtained between temperature and specific heat for a ferromagnetic substance.
