I. Yoshida et al., THE ROLE OF THE EXCITATIONS OTHER THAN MAGNONS IN THE TEMPERATURE-DEPENDENCE OF MAGNETIZATION IN A METALLIC FERROMAGNET, Physica. B, Condensed matter, 237, 1997, pp. 509-511
By showing that the phonons and other excitations also play roles as i
mportant as that of the magnons in determining magnetization we point
out the necessity of a fundamental reexamination of our current unders
tanding of itinerant electron ferromagnetism.
