摘要：

The temperature behaviour of the local magnetic fields at La-139 nuclei in various ferromagnetic LaMnO3-based compounds has been studied. The results are compared with magnetization and rf magnetic susceptibility measurements of the same samples. A qualitative correlation has been found: the greater the degree of spatially nonuniform magnetic ordering, the higher are the values of the local field and the Curie temperature. The interpretation is based on the assumption of spatially nonuniform magnetic order in the samples.
