摘要
The magneto-electric behaviors of La0.67-xNdxSr0.33MnO3 system were studied by the measurement of M - T curve, ESR curve, infrared spectra, Raman spectra, rho - T curve and MR - T curve of the La0.67-xNdxSr0.33MnO3 system (x=0.00, 0.10, 0.20, 0.30, 0.40). The experiment result shows that with the Nd doping increasing, the magnetic structure of the system transforms from the long-range ferromagnetic order to spin cluster glass state; for the samples with x=0.30 and 0.40, the phase separation occurs at the temperature high above T-c; The transport property exhibits change with the Nd doping increasing. Magneto-electric behaviors of the system and CMR effect attributes to lattice effect and interface tunneling effect relating to the spin.
