摘要

The magnetic properties of La_(2-2x)Sr_(1+2x)Mn_2O_7 polycrystals (x = 0.3, 0.35, 0.4) are studied over a broad temperature range 80-600 K. Quasi-two-dimensional manganites have a complex magnetic structure that undergoes several transitions from one type of magnetic ordering to another. A specific feature of these manganites is a hyperbolic dependence of inverse susceptibility in the transition region from the magnetically ordered to paramagnetic state for T > 360 K. This suggests the onset of ferrimagnetism. Electron irradiation to a fluence Φ = 1 * 10~(18) electrons/cm~2 is shown to have no effect on the long-range magnetic order while favoring the formation of paramagnetic polarons and of an inhomogeneous paramagnetic state.
