Spin-wave theory for dimerized ferromagnetic chains
Alexander Herzog, Peter Horsch, Andrzej M. Oles +1
We describe a Peierls dimerization which occurs in ferromagnetic spin chains at finite temperature, within the modified spin-wave theory. Usual spin-wave theory is modified by intr…

Thermally activated Peierls dimerization in ferromagnetic spin chains
J. Sirker, A. Herzog, A. M. Oles +1
We demonstrate that a Peierls dimerization can occur in ferromagnetic spin chains activated by thermal fluctuations. The dimer order parameter and entanglement measures are studied…
