Heavy Fermion State in Extremely Low Carrier Substance

在极低载波集中的重型费米状态不能通过简单扩展的精确解决方案的单有效性kondo问题。这个问题是由我们十年前根据我们的一些CeSb和CeBi结果得出的。在这个项目期间，在这个赠款援助支持下，我们可以发现这些极低的载波物质的一些异常性质，并且可以通过改进超高温家具的优良的单一晶体，其中详细描述在文件1中）。在低载波中找到的重费米状态可以归类为后续;1）重费米状态，在磁序中不减少全磁时刻： CeBi， CeSb， CeAs， CeP（参考文献2-参考文献11）2）磁序中具有亚减磁时刻的重费米状态： YbP， YbAs（ref 12 - ref 15）3）无磁序的重费米状态： Yb_4As_3 （ref 16 - ref 24）4）无磁序的重费米状态：无磁序的Sm_3Se_4b）带磁序的Sm_3Te_4

The Heavy Fermion state in extremely low carrier concentration cannot be understood by simple extension of exact solution of single impurity kondo problem. This problem have been pointed out by us since ten years ago based on our some results of CeSb and CeBi. During this project term supported by this Grant-in-Aid we could discovered the several anomalous properties of these extremely low carrier substance and could get excellent good single crystal by improvement of ultra high temperature furnace, which is described in detail in paper 1). The Heavy Fermion state in low carrier have found out to be classified as following ;1) Heavy Fermion state with no reduction full magnetic moment in magnetic order : CeBi, CeSb, CeAs, CeP (ref 2 ー ref 11)2) Heavy Fermion state with substantial reduction magnetic moment in magnetic order : YbP, YbAs (ref 12 - ref 15)3) Heavy Fermion state without any magnetic order : Yb_4As_3 (ref 16 - ref 24)4) Heavy Fermion state without free carriera) without magnetic order Sm_3Se_4b) with magnetic order Sm_3Te_4
