| Popis: | Ferromagnetic resonance (FMR) has been measured in the temperature range of 77–296K for a La 0 · 8 Sr 0 · 2 MnO z (LSMO) film and a YBa 2 Cu 3 O y /La 0 · 8 Sr 0 · 2 MnO z /YBa 2 Cu 3 O y (YBCO/LSMO/YBCO) trilayered film. The spectra are highly asymmetric and can be decomposed into two Lorentzian signals. The temperature dependence of the resonance fields and signal intensities are not so different between the LSMO film and the YBCO/LSMO/YBCO trilayered film, but that of the resonance line width is changed when the LSMO layer is sandwiched by YBCO layers. These results suggest that the dynamical properties of the spin state in manganese ions changed when the LSMO layer was sandwiched by YBCO layers. |
