Effective Spin Hamiltonian

Abstract

In the introduction, definition of Hamiltonian (Relativistic & Non-Relativistic), Euler’s equation and Schrodinger’s time dependent equation are used. Hamiltonian field theory (given by Pruskin) is used Anderson Model and Jacobian Transformation are applied. Perturbation and Green function are used. Dimmock Hamiltonian, Dugaev and Litvinov spins (S₁ and S₂) are used. Heff. in  is obtained. Various temperature and band parameters for  for x = 0.1 & x = 0.01 are listed in table.
