Tuning J $_{1}$ -J $_{2}$ in Quasi-2D Triangular Lattice Antiferromagnet $I^\pm$ -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…
