We report neutron, X-ray absorption, and resonant X-ray spectroscopy of magnetic excitations in the new heavy-fermion van-der-Waals superconductor CeSiI. We determined effective Ha…
Field-induced magnetic phase transition driven by a ground state level-crossing in CsErSe
Hope Whitelock, Allen O. Scheie, Marissa McMaster +12
We report a comprehensive study of the low-temperature magnetic properties of the insulating rare-earth triangular magnet CsErSe. We uncover a field-induced level crossing at t…
Hidden frustration in the triangular-lattice antiferromagnet NdCd3P3
Juan R. Chamorro, Steven J. Gomez Alvarado, Dibyata Rout +6
We report a study of the magnetic ground state and crystal electric field (CEF) scheme in the triangular-lattice antiferromagnet NdCdP. Combined neutron scattering, magneti…
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…
Nonperturbative Semiclassical Spin Dynamics for Ordered Quantum Magnets
Hao Zhang, Tianyue Huang, Allen O. Scheie +7
In ordered quantum magnets where interactions between elementary excitations dominate over their kinetic energy, perturbative approaches often fail, making non-perturbative methods…

Allen O. Scheie, Sabrina J. Li, Stephen D. Wilson +1
A growing list of Ce-based magnets have shown an extra and heretofore unexplained crystal electric field (CEF) mode at high energies. We describe a process whereby an optical phono…
Pressure evolution of coplanar antiferromagnetism in heavy-fermion CeCoAlGe
M. O. Ajeesh, A. O. Scheie, Yu Liu +4
CeAlGe ( Co, Ir, Ni or Pd) are heavy-fermion materials and host a variety of ground states ranging from magnetism to non-Fermi liquid behavior. The Co, Ir,…
