Field Tunable Magnetic Transitions of CsCo2(MoO4)2(OH): A Triangular Chain Structure with a Frustrated Geometry
Liurukara D Sanjeewa, V. Ovidiu Garlea, Randy S. Fishman +7
Identifying and characterizing new magnetic systems with Co2+ ions can enhance our understanding of quantum behavior since Co2+ can host a pseudospin-1/2 magnetic ground state. Und…
Zig-Zag magnetic order and potential Kitaev interactions in the spin-1 honeycomb lattice KNiAsO
K. M. Taddei, V. O. Garlea, A. M. Samarakoon +6
Despite the exciting implications of the Kitaev spin-Hamiltonian, finding and confirming the quantum spin liquid state has proven incredibly difficult. Recently the applicability o…
NaCo2(SeO3)2(OH): Competing Magnetic Ground States of a New Sawtooth Structure with 3d7 Co2+ Ions
Liurukara D. Sanjeewa, V. Ovidiu Garlea, Keith M. Taddei +5
While certain magnetic sublattices have long been known theoretically to give rise to emergent physics via competing magnetic interactions and quantum effects, finding such configu…
Nearly-Resonant Crystalline-Phononic Coupling in Quantum Spin Liquid Candidate CsYbSe
Yun-Yi Pai, Claire E. Marvinney, Liangbo Liang +10
CsYbSe, a recently identified quantum spin liquid (QSL) candidate, exhibits strong crystal electric field (CEF) excitations. Here, we identify phonon and CEF modes with Raman s…
Synthesis and Anisotropic Magnetism in Quantum Spin Liquid Candidates YbSe ( = K and Rb)
Jie Xing, Liurukara D. Sanjeewa, Andrew F. May +1
Quantum spin liquid (QSL) state in rare-earth triangular lattice has attracted much attention recently due to its potential application in quantum computing and communication. Here…
Witnessing quantum criticality and entanglement in the triangular antiferromagnet KYbSe
A. O. Scheie, E. A. Ghioldi, J. Xing +20
The Heisenberg triangular lattice quantum spin liquid and the phase transitions to nearby magnetic orders have received much theoretical attention, but clear experimental manifesta…
