摘要:

Sn_(0.8)Ag_(0.2)Te是一种新的超导体,Tc ~ 2.4K。用比热测量法研究了Sn_(0.8)Ag_(0.2)Te在磁场下的超导特性。超导转变时比热跃变的幅度证实了超导体的本质,其幅度与全能隙超导性一致。上临界场估计比热和电阻率测量下磁场。霍尔系数为正,表明Ag在Sn0.8Ag0.2Te中充当p型掺杂剂。

英文摘要:

Sn0.8Ag0.2Te is a new superconductor with Tc ~ 2.4 K. The superconducting properties of Sn0.8Ag0.2Te have been investigated by specific heat measurements under magnetic fields. Bulk nature of superconductivity was confirmed from the amplitude of the specific heat jump at the superconducting transition, and the amplitude is consistent with fully-gapped superconductivity. Upper critical field was estimated from specific heat and electrical resistivity measurements under magnetic fields. The Hall coefficient was positive, suggesting that the Ag acts as a p-type dopant in Sn0.8Ag0.2Te.
