摘要:

本文利用极化中子反射率实验研究了超导电性(S)对铁磁性(FM)(逆邻近效应)的影响。结合镜面反射和漫反射强度的测量,有可能获得完整的图片的磁化变化在S/FM分层系统,如磁化旋转,畴态形成,在S层的磁化诱导等,以增加弱磁信号,我们建议使用增强中子驻波制度(如波导)。在以前的工作中,我们已经做了计算,以增加增强因子。在这里,我们提出的S/FM样品和证明其结构,磁性,超导和中子波导特性的准备集的结果。

英文摘要:

This work is devoted to experimental study of influence of superconductivity (S) on ferromagnetism (FM) (inverse proximity effects) with the help of Polarized Neutron Reflectivity. Combining meausurements of specular and diffuse intensities it is possible to obtain full picture of magnetization change in S/FM layered systems like magnetization rotation, domain state formation, inducing of magnetization in S layer, etc. To increase weak magnetic signal we propose to use enhanced neutron standing wave regime (e.g. waveguides). In previous work we have made calculation to increase enhcanced factor. Here we present results of preparation sets of S/FM samples and attestation of their structural, magnetic, superconducting and neutron waveguide properties.
