摘要：
The Mn-55 NMR has been measured in LaxSr1-xMnO3 for x=0.2 and 0.3 as a function of temperature. in zero field and in field. The samples had a room temperature resistivity of 10(-1) ohm-cirt, and the magnetization showed a sharp FM transition 312 K. The zero field FM frequency follows T-3/2 power law at both x values consistent with the simple magnon model. A second feature at lower frequency of uncertain origin is observed.
