项目摘要
The research achievements include:(a) that the origin of high-TCsuperconductivity (HTSC) in multilayer high-Tc copper-oxides materials is a super-exchange interaction that induces antiferromagnetic ordering;(b) that new iron-based HTSC can be well explained using a multiple gap sign-reversing s±wave model with isotropic gaps and its TCis highest when the FeAs local structure is regular tetrahedral;(c) that the room-temperature magneto-electric effect was realized in Sr_3Co_2Fe_24O_41at very weak magnetic field;(d) that the theory has theoretically shown that the quantum critical point of valence transitions is induced by a magnetic field, unraveling the existence of a novel quantum criticality
研究成果包括:(a)多层高温铜氧化物材料中高温超导(HTSC)的起源是诱导反铁磁有序化的超交换相互作用;(b)新型铁基HTSC可以很好地使用具有各向同性间隙的多间隙符号反转 s±波模型进行解释,当 FeAs 局部结构为正四面体时,其 TC 最高;(c) 室温在极弱磁场下,Sr_3Co_2Fe_24O_41实现了磁电效应;(d)该理论从理论上证明了价态跃迁的量子临界点是由磁场引起的,揭示了一种新的量子临界点的存在
