Localized-magnon states in strongly frustrated quantum spin lattices
Recent developments concerning localized-magnon eigenstates in strongly frustrated spin lattices and their effect on the low-temperature physics of these systems in high magnetic fields are reviewed. After illustrating the construction and the properties of localized-magnon states we describe the...

The author is indebted to O. Derzhko, A. Honecker, H.-J. Schmidt, J. Schnack, and J. Schulenburg for the fruitful collaboration in the field of localized-magnon states in frustrated antiferromagnets. Most of the results discussed in the paper are based on common publications with these colleagues. In particular, I thank J. Schulenburg for many valuable discussions and hints. Furthermore I thank H. Frahm for directing my attention to the flat-band ferromagnetism.

Recent developments concerning localized-magnon eigenstates in strongly frustrated spin lattices
and their effect on the low-temperature physics of these systems in high magnetic fields are
reviewed. After illustrating the construction and the properties of localized-magnon states we describe
the plateau and the jump in the magnetization process caused by these states. Considering
appropriate lattice deformations fitting to the localized magnons we discuss a spin-Peierls instability
in high magnetic fields related to these states. Last but not least we consider the degeneracy of
the localized-magnon eigenstates and the related thermodynamics in high magnetic fields. In particular,
we discuss the low-temperature maximum in the isothermal entropy versus field curve and
the resulting enhanced magnetocaloric effect, which allows efficient magnetic cooling from quite
large temperatures down to very low ones. |
