摘要：

The temperature dependence of the magnetic moment measured by a superconducting quantum interference device magnetometer in La1-xNaxMnO3 (x = 0.1, 0.15. 0.2) ferromagnetic perovskites is compared with the temperature dependence of the NMR frequency on Mn-55 and La-139 nuclei. In the region close to T-C, the NMR relaxation rate is also determined. From the results it follows that the phase transition is continuous for all Na concentrations studied.
