Abstract
We show that the driving force for the spiral-to-ferromagnet transition in Dy and Tb is the energy of cylindrical symmetry associated with the lowest order magnetostriction effects. We also point out that the experimental temperature dependence of the spinwave energy gap for Tb does not agree with that calculated using the frozen-lattice approximation suggested by Turov and Shavrov for magnetoelastic effects.Keywords
