Fermions and bosons in nonsymmorphic PdSb2 with sixfold degeneracy
Ramakanta Chapai, Yating Jia, W. A. Shelton +6
PdSb2 is a candidate for hosting 6-fold-degenerate exotic fermions (beyond Dirac and Weyl fermions).The nontrivial band crossing protected by the nonsymmorphic symmetry plays a cru…
Anomalous Magnetic Behavior in Ba2CoO4 with Isolated CoO4 Tetrahedra
Qiang Zhang, Guixin Cao, Feng Ye +9
The dimensionality of the electronic and magnetic structure of a given material is generally predetermined by its crystal structure. Here, using elastic and inelastic neutron scatt…
Structure-Property Relationship in Layered BaMn2Sb2 and Ba2Mn3Sb2O2
Qiang Zhang, Zhenyu Diao, Huibo Cao +5
Layered transition-metal compounds have received great attention owing to their novel physical properties. Here, we present the structural, electronic, thermal, and magnetic proper…
Mn-induced magnetic symmetry breaking and its correlation with the metal-insulator transition in bilayered Sr3(Ru1-xMnx)2O7
Qiang Zhang, Feng Ye, Wei Tian +8
Bilayered Sr3Ru2O7 is an unusual metamagnetic metal with inherently antiferromagnetic (AFM) and ferromagnetic (FM) fluctuations. Partial substitution of Ru by Mn results in the est…
Spin Density wave instability in a ferromagnet
Yan Wu, Zhenhua Ning, Huibo Cao +7
Ferromagnetic (FM) and incommensurate spin-density wave (ISDW) states are an unusual set of competing magnetic orders that are seldom observed in the same material without applicat…
Hidden Phases Revealed at the Surface of Double-Layered Sr3(Ru1-xMnx)2O7
Chen Chen, Jisun Kim, V. B. Nascimento +8
Double-layered Sr3Ru2O7 has received phenomenal consideration because it exhibits a plethora of exotic phases when perturbed. New phases emerge with the application of pressure, ma…
