From the Foreword:

"Only rarely does one find translations from Russian of scientific material that read as if they had originally been written in English. Mr. Tybulewicz achieved this objective and is to be commended for it.
The Present monograph will appeal to the students of magnetism and others who appreciated the Green function methods previously introduced by Bonch-Bruevich and Tyablikov, but who felt that the sections on magnetism in the earlier book were too compact. ...

Tyablikov might well have entitled the present monograph "Theories of the Heisenberg Model" for he treats this model from many point of view: (a) ground state properties (ferromagnetic, antiferromagnetic, helical, etc.), (b) dynamics and quantum mechanics, and (c) thermodynamical and statistical properties. Concepts of spin-wave theory, molecular-field theory, ferromagnetic resonance, and of Bogolyubov's "method of approximate second-quantization" are developed in the present context well before the Green function theory is even introduced. Some recent developments, such as H.B.Callen's improved decoupling scheme, are described, and, in general, the text covers many of the interesting applications of the formalism to cooperative magnetism..."
