Notes:
The thermodynamics of a one-dimensional diluted Heisenberg magnet of classical spins in the presence of single ion anisotropy is calculated. This model is representative of systems such as (CD3)4NMnxCu1−xC13 and CsMnxMg1−xBr3. The magnetization susceptibility, energy, and specific heat are determined as functions of the magnetic concentration and single ion anisotropy for both ferromagnetic and antiferromagnetic couplings. Spin-spin correlation functions and the elastic scattering function are also calculated for various values of anisotropy and spin concentration in these systems. The solutions presented are obtained as sums over the properties of finite length chains weighted by their probabilities of occurrence in the diluted system.
