Magnetic order and excitations in CeTiBi and CeZrBi
Pyeongjae Park, Qianli Ma, Wei Tian +7
The R3MBi5 rare-earth intermetallics (R = rare earth, M = Ti, Zr, Sc) provide a versatile platform to explore how Kondo hybridization, RKKY exchange, magnetic frustration, and brok…
Skyrmion and Meron Crystals in Intermetallic GdRuAl: Microscopic Model Insights into Chiral Phases
Jiajun Mo, Leandro M. Chinellato, Fletcher Williams +14
Topological spin textures in frustrated intermetallics hold great promise for spintronics applications. However, understanding their origin and properties remains a significant cha…
Intrinsic disorder in the candidate quantum spin ice PrZrO
T. J. Hicken, P. Meadows, D. Prabhakaran +13
Quantum spin liquids with long-range entanglement are of great interest for applications in quantum technology. The quantum spin ice PrZrO is a promising example, where…
Crystal field splittings and magnetic ground state of the square-lattice antiferromagnets YbBi2ClO4 and YbBi2IO4 with Jeff = 1/2
Pyeongjae Park, Qianli Ma, G. Sala +5
We report on the crystal field level splitting and magnetic ground state of the Jeff = 1/2 square lattice antiferromagnets YbBi2ClO4 and YbBi2IO4 using powder inelastic neutron sca…
Quantum and classical spin dynamics across temperature scales in the S = 1/2 Heisenberg antiferromagnet
Pyeongjae Park, G. Sala, Daniel M. Pajerowski +6
Using the framework of semi-classical Landau-Lifshitz dynamics (LLD), we conduct a systematic investigation of the temperature-dependent spin dynamics in the S = 1/2 Heisenberg squ…
Quantum magnetism in the frustrated square lattice oxyhalides YbBi2IO4 and YbBi2ClO4
Pyeongjae Park, G. Sala, Th. Proffen +3
Square-lattice systems offer a direct route for realizing 2D quantum magnetism with frustration induced by competing interactions. In this work, the square-lattice materials YbBi2I…
Dynamical scaling as a signature of multiple phase competition in YbTiO
Allen Scheie, Owen Benton, Mathieu Taillefumier +5
is a celebrated example of a pyrochlore magnet with highly-frustrated, anisotropic exchange interactions. To date, attention has largely focused on its unusual, s…
Octupolar vs Néel Order in Cubic 5 double perovskites
Dalini D. Maharaj, Gabriele Sala, Matthew B. Stone +7
We report time-of-flight neutron spectroscopic and diffraction studies of the 5 cubic double pervoskite magnets, BaMOsO ( = Zn, Mg, Ca). These cubic materials are a…
