Spin Waves in the Dilute Heisenberg Ferromagnet
The energy of long wave length spin waves in dilute Heisenberg ferromagnets is calculated. It is shown that spin waves can exist only within an infinite cluster of magnetic spins and that such spin waves are mechanically stable. Heuristic arguments based on dimensionality of the infinite cluster imply that there is no thermal instability of the type discussed by Mermin and Wagner. Thus, the cri...
متن کاملSpin Waves and Long-Range Order in the Diluted Heisenberg Ferromagnet at Zero Temperature
The variational treatment of spin waves in the randomly diluted Heisenberg ferromagnet at zero temperature is studied. It is argued that a convenient variational principle for the excitation spectrum of an alloy is difficult to formulate rigorously. However, at extremely long wavelengths a simple variational calculatation probably has approximate validity providing localized excitations in isol...

متن کاملTemperature cycles in the Heisenberg spin glass
We study numerically the nonequilibrium dynamics of the three-dimensional Heisenberg Edwards-Anderson spin glass submitted to protocols during which temperature is shifted or cycled within the spin glass phase. We show that partial rejuvenation and perfect memory effects can be numerically observed and study both effects in detail. We quantitatively characterize their dependences on parameters ...
متن کاملQuantum Stability for the Heisenberg Ferromagnet
Highly spinning classical strings on R×S are described by the Landau– Lifshitz model or equivalently by the Heisenberg ferromagnet in the thermodynamic limit. The spectrum of this model can be given in terms of spectral curves. However, it is a priori not clear whether any given admissible spectral curve can actually be realised as a solution to the discrete Bethe equations, a property which ca...
