过渡金属及其合金团簇的磁性检测实验研究进展

A Research Progress on the Magnetism Detection Experiment of Transition Metal and Alloy Clusters

过渡金属及其合金团簇的磁性一直受到实验和理论工作者的广泛关注.到目前为止,Stern-Gerlach磁偏转分子束实验是过渡金属及其合金团簇磁性检测的最可靠技术.本文介绍了Stern-Gerlach磁偏转分子束的实验装置、磁性检测原理及其磁性检测的影响因素,并对一元过渡金属团簇和二元过渡金属合金团簇的磁性检测实验研究进展作了全面的总结概述.

Over the last two decades,much attention has been paid to the magnetism of transition metal（TM） and alloy clusters both theoretically and experimentally.Up to now,the Stern-Gerlach molecular beam deflection experiment is the most reliable technique for the magnetism of detection of transition metal and alloy clusters.In this paper,the apparatus of the Stern-Gerlach molecular beam deflection experiment,the principle of work and the influence factor of the magnetism detection are introduced in detail.Meanwhile,the experiment research progress of the magnetism measuring for pure TM clusters and bimetallic TM alloy clusters have also been summarized systematically.
