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 Pb,_xMnxA (A = Te.Se.S) is obtained. Various temperature and band parameters for Pb Mn Te for x = 0.1 & x = 0.01 are listed in table.
