摘要：
We have grown Ni/Pt multilayers with Pt buffer layer, by evaporation under UHV conditions on glass substrates maintained at 300 K. The magnetic properties of Ni/Pt multilayers are examined as a function of Ni layer thickness Ni. The temperature dependence of the spontaneous magnetization M(T) is well described by a T-3/2 law in all multilayers. A spin-wave theory has been used to explain the temperature dependence of the magnetization and the approximate values for the bulk exchange interaction J(b), surface exchange interaction J(S) and the interlayer coupling strength J(I) for various Ni layer thicknesses have been obtained.
