摘要：

The magnetic properties of the manganese oxide compounds La1-xSrxMnO3 are studied by means of the double-time Green's function. The phase diagram, magnetization, spin-wave dispersion, and spin-wave stiffness are obtained within the random phase approximation. Our results are in agreement with other theoretical and experimental results. (C) 2010 American Institute of Physics. [doi:10.1063/1.3505761]
