Field-Induced Selective Spin Gap Closure and Quantum Criticality in BaNdZnS
Sangyun Lee, A. J. Woods, B. Billingsley +11
We report thermodynamic evidence for field-induced mode-selective quantum criticality in the layered rare-earth magnet BaNd2ZnS5 (BNZS). Below the Neel temperature TN = 2.9 K, spin…
Magnetization Plateaus in the Spin-Orbit Coupled Bilayer Triangular Lattice Antiferromagnet Rb2Co2(SeO3)3
Shengzhi Zhang, Gabriel Silva Freitas, Vivien S. Zapf +8
Geometric frustration among competing spin exchanges can give rise to novel quantum phases by enhancing fluctuations that drive magnetic systems beyond the classical regime. We inv…
Random singlet physics in exchange disordered 2D triangular YbCuSe
Caitlin S. T. Kengle, Sean M. Thomas, Roman Movshovich +5
Quantum spin liquid (QSL) phases exist in theory, but real candidate QSL materials are often extraordinarily sensitive to structural defects which disrupt the ground state. Here, w…
Quantum Order by Disorder: A Key to Understanding the Magnetic Phases of BaCo(AsO)
Sangyun Lee, Shengzhi Zhang, S. M. Thomas +6
BaCo(AsO) (BCAO), a honeycomb cobaltate, is considered a promising candidate for materials displaying the Kitaev quantum spin liquid state. This assumption is based on…
Out-of-plane magnetic phase diagram of Kitaev quantum spin liquid candidate Na2Co2TeO6
Shengzhi Zhang, Sangyun Lee, Eric Brosha +4
We have investigated the magnetic properties and mapped out the phase diagram of the honeycomb magnet Na2Co2TeO6 with Co 3d7 in out-of-plane magnetic fields. This material has prev…
Magnetic field-temperature phase diagram of spin-1/2 triangular lattice antiferromagnet KYbSe
Sangyun Lee, Andrew J. Woods, Minseong Lee +7
A quantum spin liquid (QSL) is a state of matter characterized by fractionalized quasiparticle excitations, quantum entanglement, and a lack of long-range magnetic order. However,…
