采用超高真空交替沉积技术，在MgO（001）衬底上用三种元素靶制备了具有Cr缓冲层的Co2 MnSn薄膜。这些薄膜表现出良好的结晶度，外延关系为MgO（001）//Cr（001）//Co2 MnSn（001）和MgO[100]//Cr[110]//Co2 MnSn [110]。[Co_2MnSn（2.2nm）/Cr（0.9nm）]_（10）多层膜也具有高的晶体质量。利用磁化强度测量和119 Sn穆斯堡尔谱研究了Co2 MnSn薄膜的磁性。通过穆斯堡尔效应测量观察到的超精细场表明，在200 ℃下生长的样品中，Sn周围的短程有序度与体样品一样好。
Thin films of Co2MnSn were prepared on MgO(001) substrates with a Cr-buffer layer from three elemental targets by ultrahigh-vacuum alternate deposition. These films showed good crystallinity, and the epitaxial relations were found to be MgO(001)//Cr(001)//Co2MnSn(001) and MgO[100]//Cr[110]//Co2MnSn[110]. [Co2MnSn(2.2nm)/Cr(0.9nm)]10multilayers were also prepared with high crystallographic quality. The magnetic properties of Co2MnSn films were studied by magnetization measurements and119Sn Mössbauer spectroscopy. Hyperfine fields observed by Mössbauer effect measurements showed that the degree of short range order around Sn in the samples grown at 200∘C was as good as that in bulk samples.
