Classical one-dimensional Heisenberg model with an interaction of finite range

摘要: Abstract It is shown that the thermodynamic quantities and spin correlation functions of classical Heisenberg model on a linear chain are expressed in terms eigenvalue with smallest absolute value corresponding eigenfunction homogeneous integral equation, where range interaction assumed to be finite. The magnetization susceptibility at nonzero external magnetic fields given as function temperature, for case nearest neighbour ferromagnetic antiferromagnetic interaction. Efforts paid determine properties near zero temperature.
