Description
Results are found for the correlation dynamic functions (or the correspondent green functions) between any combination including pairs of electronic anel nuclear spin operators in an antiferromagnet semi-infinite media., at low temperature T <<TN. These correlation functions, are used to investigate, at the same time, the properties of surface spin waves in volume and surface. The dispersion relatons of nuclear and electronic spin waves coupled modes, in surface are found, resolving a system of linearized equatons of spin operators a system of linearized equations of spin operators.

Resultados sao encontrados para as funcoes dinamicas de correlacao (ou suas funcoes de Greens correspondentes) entre qualquer combinacao incluindo pares de operadores de spins eletronicos e nucleares em um meio semi-infinito antiferromagneto, a baixas temperaturas T << TN. Essas funcoes de correlacao sao usadas para investigar ao mesmo tempo as propriedades de ondas de spins superficiais no volume e na superficie. As relacoes de dispersao dos modos acoplados de ondas de spins eletronicas e nucleares na superficie sao encontradas resolvendo um sistema de equacoes linearizadas de operadores de spins.
