Long-range magnetic order with disordered spin orientations in a high-entropy antiferromagnet
Yao Shen, Guangkai Zhang, Qinghua Zhang +12
Disorder in magnetic systems typically suppresses long-range order, promoting short-range states such as spin glasses and magnetic clusters. This is particularly prominent in high-…
Dynamic nanoscale spatial heterogeneity in a perovskite to brownmillerite topotactic phase transformation
Nicolò D'Anna, Erik S. Lamb, Robin Glefke +5
Phase transitions are omnipresent in modern condensed matter physics and its applications. In solids, first-order phase transformations typically occur by nucleation and growth und…
Direct Fabrication of a Superconducting Two-Dimensional Electron Gas on KTaO3(111) via Mg-Induced Surface Reduction
Chun Sum Brian Pang, Bruce A. Davidson, Fengmiao Li +16
Two-dimensional electron gases (2DEGs) at the surfaces of KTaO3 have become an exciting platform for exploring strong spin-orbit coupling, Rashba physics, and low-carrier-density s…
Fermi surface and Berry phase analysis for Dirac nodal line semimetals: cautionary tale to SrGa and BaGa
Yuxiang Gao, Yichen Zhang, Shiming Lei +8
A Berry phase of odd multiples of inferred from quantum oscillations (QOs) has often been treated as evidence for nontrivial reciprocal space topology. However, disentangling t…
Layer controlled orbital selective Mott transition in monolayer nickelate
Byungmin Sohn, Minjae Kim, Sangjae Lee +14
Dimensionality and electronic correlations are crucial elements of many quantum material properties. An example is the change of the electronic structure accompanied by the loss of…
Structural Phase Separation and Enhanced Superconductivity in La1.875Ba0.125CuO4 under Uniaxial Strain
Baizhi Gao, Ehsan Nikbin, Graham Johnstone +9
Strain engineering has attracted significant attention in recent years due to its capability in tuning lattice and electronic structures of quantum materials. Using moderate uniaxi…
