Abstract
The theory of low-dimensional quantum singlet-triplet Heisenberg ferromagne ts is formulated. The temperature dependencies of the susceptibilities, the correlation lengths and the correlation functions for the collinear phases of the singlet-triplet ferromagnet are found. The influence of external ma gnetic fields on the magnetisation is considered. (C) 1999 Elsevier Science B.V. All rights reserved.
