O.D. and J.R. acknowledge the kind hospitality of the
MPIPKS-Dresden in the end of 2006. O.D. is indebted to
Magdeburg University and to Wroclaw University for
their hospitality in the autumn of 2006. A part of the numerical
calculations was performed using Jörg
Schulenburg’s spinpack. We would like to thank M.E.
Zhitomirsky for useful discussions and comments on this
manuscript.

The purpose of the present paper is two-fold. On the one hand, we review some recent studies on the
low-temperature strong-field thermodynamic properties of frustrated quantum spin antiferromagnets which
admit the so-called localized-magnon eigenstates. One the other hand, we provide some complementary new
results. We focus on the linear independence of the localized-magnon states, the estimation of their degeneracy
with the help of auxiliary classical lattice–gas models and the analysis of the contribution of these states
to thermodynamics.
