Defect-induced optical magnons and local magnetic correlations in MnSb2Te4
Dhurba R. Jaishi, Bing Li, Tianxiong Han +4
Magnetic defect engineering offers a route to manipulate and control magnetic and electronic states in quantum materials. In the Mn(Bi,Sb)2Te4 family of topological magnetic insula…
Chiral Magnon Mixing by Symmetry-Breaking in Collinear Ferrimagnets
Dhurba R. Jaishi, Tyler J. Slade, S. X. M. Riberolles +8
Magnons in ferromagnets possess spin angular momentum defined by right-handed precession of the moment around the magnetization direction. In antiferromagnets with no net magnetiza…
Hidden symmetry-breaking in a kagome Ising ferromagnet
Tianxiong Han, Tyler J. Slade, Liqin Ke +15
Kagome metals can host unconventional electronic phenomena that emerge from their frustrated lattice geometry and associated band topology. Correlated electronic orders, such as ch…
Nature of quantum criticality in the Ising ferromagnet TbVSn
Tianxiong Han, R. D. McKenzie, Joanna Blawat +10
TbVSn is a topological metal where ferromagnetic Tb ions with strong uniaxial magnetic anisotropy interact with V kagome layers. Inelastic neutron scattering (INS) measurem…
Symmetry tuning topological states of an axion insulator with noncollinear magnetic order
S. X. M. Riberolles, A. M. NediÄ, B. Kuthanazhi +10
Topological properties of quantum materials are intimately related to symmetry. Here, we tune the magnetic order of the axion insulator candidate EuInAs from its broken-hel…
Spin dynamics in itinerant antiferromagnet SrCrAs
Zhenhua Ning, Pinaki Das, Y. Lee +6
SrCrAs is an itinerant antiferromagnet in the same structural family as the SrFeAs high-temperature superconductors. We report our calculations of exchange-coupling…
