摘      要：An improved sputtering method,which is named in situ oxidizing sputtering,was used to prepare periodic Ni/NiO *** studied in this letter contains 20 pairs of Ni/NiO with period about 100 *** Raman scattering,the low frequency phonon modes are hiterpreted as LA phonon folding effect,which is usually measured in superlattices with a strict periodic *** ferromagnetic resonance spectra were also recorded at room temperature with microwave frequency 9.777 *** analysis of spin wave resonance indicates that Ni sublayers are coupled with each other,which is the mechanism that surely relates to the amorphous-like NiO spacers.
