摘要
缪子自旋弛豫/旋转技术(muon spin relaxation/rotation,μSR)是一种高度灵敏的原子尺度磁性探测手段.随着μSR技术的不断发展,其在凝聚态物理研究中愈加重要.本文简要介绍pSR技术的优越性和独特性,概述近期μSR技术在凝聚态领域的几项重要进展和挑战,包括镍基超导体La3Ni2O7和(R,Sr)NiO2的磁性基态研究、笼目晶格超导体AV3Sb5(A=K,Rb)的电荷密度波研究、NaYbSe2量子自旋液体"海洋"中沉浸的自旋"磁滴"和Cr2O3磁电表面附近磁单极子的研究,并简单阐述了国际上缪子源的建设情况和升级进展.
Abstract
Muon spin relaxation/rotation(μSR)is a highly sensitive technique for investigating magnetic properties on an atomic scale.With the continuous development of this technique,the researches in condensed matter physics have been significantly promoted.Firstly,this article introduces the advantages and uniqueness of μSR technique,followed by several recent progress contributed by pSR in the field of condensed matter physics,including revealing the magnetic ground state of superconducting nickelates La3Ni2O7 and(R,Sr)NiO2,the investigation into the charge density wave in kagome lattice superconductor AV3Sb5(A=K,Rb),identifying the magnetic droplets immersed in a sea of quantum spin liquid ground state in NaYbSe2,and the exploration of magnetic monopole near a magnetoelectric surface of Cr2O3.Finally,this article summarizes the current construction status and upgrade plans of muon facilities in the world.
