Vm. Zverev et Vp. Silin, MAGNETOELASTICITY AND EFFECT OF THERMAL PHONONS ON THE MAGNETIC-PROPERTIES OF FERROMAGNETS, JETP letters, 64(1), 1996, pp. 37-41
The experimental data for a series of ferromagnets are analyzed to det
ermine quantitatively the magnetoelasticity-reduced effects of thermal
phonons on the magnetic properties of ferromagnets. It is shown that
thermal phonons have an anomalously strong effect on the magnetic prop
erties of Invar iron-platinum alloys. The effect is governed by shear
magnetoelasticity. (C) 1996 American Institute of Physics.
