重费米子超导体UPt_3的低温正常态比热及其压力特性

The Specific Heat and It's Pressure Property in Normal State at Low Temperature of Heavy Fermion Superconductor Upt_3

本文从Ｋｏｎｄｏ晶格的特点出发，采用有虚能隙存在的洛仑兹峰态密度，对重费米子超导体ＵＰｔ３的低温正常态比热及其压力特性进行了研究．结果与实验相符合．我们的结果表明，利用Ｌｏｒｅｎｔｚｉａｎ峰型态密度来讨论重费来子系统的比热等性质是较合适的．

Considering the characteristic of Kondo lattic, the specific hesat And it's pressure property in normal state at low temperature of heavy fermion superconductor Upt3 is studied.The results tally with the experimental data.The conclussion show that it is quite suitable to research the property of heavy-fermion system by using the density of states as a lorentzian peak.
