Frustration induced dimensional reduction and coexistence of long and short-range magnetic order in NdCl
Eli Zoghlin, Matthew B. Stone, Vasile O. Garlea +3
The phenomenon of frustration greatly enriches the accessible physics of quantum magnets. With this in mind we study the magnetism of \NC using a combination of bulk properties mea…
Magnetism of single crystalline breathing pyrochlore spinel AgInCr4S8
Andrew F. May, Christopher M. Pasco, V. O. Garlea +5
Single crystals of \ce{AgInCr4S8} were grown by chemical vapor transport and crystallographic ordering of Ag/In that results in a breathing pyrochlore motif of Cr was verifi…
Observation of Switchable Chiral Magnons in an Altermagnet
Zheyuan Liu, Hodaka Kikuchi, Zijun Wei +8
Chiral magnons, the quanta of handed spin waves, transport spin angular momentum without energy loss due to Joule heating. The recently discovered altermagnets were proposed to hos…
Coexistence and interaction of spinons and magnons in an antiferromagnet with alternating antiferromagnetic and ferromagnetic quantum spin chains
H. Zhang, Z. Zhao, D. Gautreau +10
In conventional quasi-one-dimensional antiferromagnets with quantum spins, magnetic excitations are carried by either magnons or spinons in different energy regimes: they do not co…
Manifolds of magnetic ordered states and excitations in the almost Heisenberg pyrochlore antiferromagnet MgCr2O4
S. Gao, K. Guratinder, V. Tsurkan +18
In spinels ACr2O4 (A=Mg, Zn) realisation of the classical pyrochlore Heisenberg antiferromagnet model is complicated by a strong spin-lattice coupling: the extensive degeneracy of…
Antiferromagnetism in the van der Waals layered spin-lozenge semiconductor CrTe3
Michael A. McGuire, V. Ovidiu Garlea, Santosh KC +4
The crystallographic, magnetic, and transport properties of the van der Waals bonded, layered compound CrTe3 have been investigated on single crystal and polycrystalline materials.…
Anisotropic exchange within decoupled tetrahedra in the quantum breathing pyrochlore Ba3Yb2Zn5O11
J. G. Rau, L. S. Wu, A. F. May +9
The low energy spin excitation spectrum of the breathing pyrochlore Ba3Yb2Zn5O11 has been investigated with inelastic neutron scattering. Several nearly resolution limited modes wi…
Disorder from order among anisotropic next-nearest-neighbor Ising spin chains in SrHoO
J. -J. Wen, W. Tian, V. O. Garlea +7
We describe why Ising spin chains with competing interactions in segregate into ordered and disordered ensembles at low temperatures (). Using elastic neutron sc…
Structural and magnetic properties of the new cobaltate series (BaSr)4-xLa2xCo4O15
V. O. Garlea, R. Jin, E. Garlea +5
We report the structural and magnetic properties of a new class of cobaltates with the chemical formula (BaSr)4-xLa2xCo4O15 (x = 0, 0.5 and 1). These compounds crystallize in a hex…
Crystals for neutron scattering studies of quantum magnetism
T. Yankova, D. Huvonen, S. Muhlbauer +8
We review a strategy for targeted synthesis of large single crystal samples of prototype quantum magnets for inelastic neutron scattering experiments. Four case studies of organic…
Continuous magnetic and structural phase transitions in Fe1+yTe
I. A. Zaliznyak, Z. J. Xu, J. S. Wen +7
We report a sequence of continuous phase transformations in iron telluride, Fe1+yTe (y~0.1), which is observed by combining neutron diffraction, magnetic susceptibility, and specif…
Absence of localized-spin magnetism in the narrow-gap semiconductor FeSb2
I. A. Zaliznyak, A. T. Savici, V. O. Garlea +2
We report inelastic neutron scattering measurements aimed at investigating the origin of the temperature-induced paramagnetism in the narrow-gap semiconductor FeSb2. We find that i…
Excitations from a chiral magnetized state of a frustrated quantum spin liquid

We study excitations in weakly interacting pairs of quantum spin ladders coupled through geometrically frustrated bonds. The ground state is a disordered spin liquid, that at high…
Magnetic and orbital ordering in the spinel MnV2O4
V. O. Garlea, R. Jin, D. Mandrus +5
Neutron inelastic scattering and diffraction techniques have been used to study the MnV2O4 spinel system. Our measurements show the existence of two transitions to long-range order…
Spin density distribution in a partially magnetized organic quantum magnet
A. Zheludev, V. O. Garlea, S. Nishihara +4
Polarized neutron diffraction experiments on an organic magnetic material reveal a highly skewed distribution of spin density within the magnetic molecular unit. The very large mag…
