高温氧化物超导体:费米液体抑或非费米液体?

High-Tc Oxide Superconductors Fermi Liquid or Non-fermi Liquid?

文章对高Ｔｃ氧化物超导体是否为费米液体问题作一评述．文中以五条标准作为费米液体的定义．就电阻率、霍耳效应、温差电势率、核磁弛豫、正电子湮灭、光电发射谱等一系列现象中出现的有关问题作了评估．对有关各主要流派作了评论．

In this paper the problem whether a high-Tc oxide superconductor is a Fermi liquid or not is reviewed. The Fermi liquid is defined by five criteria. The relevant problems which occur in a series of phenomena, including resistivity. Hall effect, nuclear magnetic relaxation. ther- moelectric power, positron annihilation and the photoehassion spectra, have been discussed. Some comments on the main schools have been made also.
