Free energy variational approach for the classical anisotropic XY model in a crystal field
L. M. Castro, A. S. T. Pires, J. A. Plascak
A variational approach for the free energy is used to study the three-dimensional anisotropic XY model in the presence of a crystal field. The magnetization and the phase diagrams…

Comment on ``Magnon wave forms in the presence of a soliton in two--dimensional antiferromagnets with a staggered field''
Denis D. Sheka
Very recently Fonseca and Pires [Phys. Rev. B 73, 012403(2006)] have studied the soliton--magnon scattering for the isotropic antiferromagnet and calculated ``exact'' phase shifts,…
