Tuning J $_{1}$ -J $_{2}$ in Quasi-2D Triangular Lattice Antiferromagnet $α$ -SrCr $_{2}$ O $_{4}$ via Uniaxial Pressure

Jazzmin Victorin, Shreenanda Ghosh, Seyed Koohpayeh +2

Triangular lattice antiferromagnets first attracted attention as a frustrated magnetic lattice which can serve as a platform to realize the resonating valence bond state. While the…

Physically-Constrained Autoencoder-Assisted Bayesian Optimization for Refinement of High-Dimensional Defect-Sensitive Single Crystalline Structure

Joseph Oche Agada, Andrew McAninch, Haley Day +6

Physical properties and functionalities of materials are dictated by global crystal structures as well as local defects. To establish a structure-property relationship, not only th…

Intrinsic quantum disorder in Yb2Ti2O7 and the quantum S=1/2 pyrochlore phase diagram

Shang-Shun Zhang, Anish Bhardwaj, S. M. Koohpayeh +4

We present an experimental and theoretical study of the anisotropic pyrochlore phase diagram. Inelastic field-dependent neutron scattering on Yb $_{2}$ Ti $_{2}$ O $_{7}$ shows intrinsic broa…

Quenched Disorder in the Triangular Lattice Antiferromagnet YbZn $_{2}$ GaO $_{5}$

Leshan Zhao, Tong Chen, Matthew B. Stone +4

We investigate the crystal electric field (CEF) excitations of Yb $^{3 +}$ ions in powder samples of the triangular-lattice rare-earth-based antiferromagnet YbZn $_{2}$ GaO $_{5}$ using ine…

Pressure control of magnetic order and excitations in the pyrochlore antiferromagnet MgCr $_{2}$ O $_{4}$

L. S. Nassar, H. Lane, B. Haberl +4

MgCr $_{2}$ O $_{4}$ is one of the best-known realizations of the pyrochlore-lattice Heisenberg antiferromagnet. The strong antiferromagnetic exchange interactions are perturbed by sm…

Quantum paramagnetism in a non-Kramers rare-earth oxide: Monoclinic $P r_{2} T i_{2} O_{7}$

Huiyuan Man, Alireza Ghasemi, Moein Adnani +8

Little is so far known about the magnetism of the $A_{2} B_{2} O_{7}$ monoclinic layered perovskites that replace the spin-ice supporting pyrochlore structure for $r_{A} / r_{B} > 1.78$ . We sh…

Dynamical scaling as a signature of multiple phase competition in Yb $_{2}$ Ti $_{2}$ O $_{7}$

Allen Scheie, Owen Benton, Mathieu Taillefumier +5

$Y b_{2} T i_{2} O_{7}$ is a celebrated example of a pyrochlore magnet with highly-frustrated, anisotropic exchange interactions. To date, attention has largely focused on its unusual, s…

Quantum Critical Magnetic Excitations in Spin-1/2 and Spin-1 Chain Systems

Y. Xu, L. S. Wang, Y. Y. Huang +9

The study of CoNb $_{2}$ O $_{6}$ sits at the confluence of simplicity and complexity: on one hand, the model for Ising chains -- the building blocks of CoNb $_{2}$ O $_{6}$ -- in a transverse f…
