摘要：
The parameters of the planar magnetic anisotropy and exchange interaction both in the epitaxial manganite/ruthenate (La(0.7)sr(0.3)MnO(3)/SrRuO3) heterostructure and in the manganite film (La0.7Sr0.3MnO3) have been studied using the ferromagnetic resonance (FMR) technique in the temperature range of 30-300 K. The temperature dependence of bilinear and biquadratic interlayer exchange interaction has been obtained from the angular dependences of the FMR spectra. It is shown that the interaction is determined by the short-wavelength oscillations of the interlayer exchange which are associated with the magnetic ordering of the interlayer between the ferromagnetic layers.
