Accessing Few-Layer CrI Magnetoelasticity Through Bulk Single Crystals
J. Arneth, M. Möller, D. A. S. Kaib +9
The persistence of ferromagnetic long-range order in monolayers of the van der Waals semiconductor CrI opens new routes for spintronic applications based on two-dimensional qua…
Nonlinear Spectroscopy as a Magnon Breakdown Diagnosis and its Efficient Simulation
David A. S. Kaib, Marius Möller, Roser Valenti
Identifying quantum spin liquids, magnon breakdown, or fractionalized excitations in quantum magnets is an ongoing challenge due to the ambiguity of possible origins of excitation…
Anisotropy of the zigzag order in the Kitaev honeycomb magnet -RuBr
John S. Pearce, David A. S. Kaib, Zeyu Ma +5
Kitaev materials often order magnetically at low temperatures due to the presence of non-Kitaev interactions. Torque magnetometry is a very sensitive technique for probing the magn…
Anisotropic magnetic interactions in a candidate Kitaev spin liquid close to a metal-insulator transition
Zeyu Ma, Danrui Ni, David A. S. Kaib +6
In the Kitaev honeycomb model, spins coupled by strongly-frustrated anisotropic interactions do not order at low temperature but instead form a quantum spin liquid with spin fracti…
Theory of Intrinsic Phonon Thermal Hall Effect in -RuCl
Ramesh Dhakal, David A. S. Kaib, Kate Choi +3
We apply a recently developed first-principles based approach for treating generic spin-phonon couplings in materials with strong spin-orbit coupling to study -RuCl. Of part…
Understanding the microscopic origin of the magnetic interactions in CoNbO

Motivated by recent reports of a quantum disordered ground state in the triangular lattice compound NaRuO, we derive a magnetic model for this system by means…
Magnetic anisotropy reversal driven by structural symmetry-breaking in monolayer α-RuCl3
Bowen Yang, Yin Min Goh, Suk Hyun Sung +14
Layered α-RuCl3 is a promising material to potentially realize the long-sought Kitaev quantum spin liquid with fractionalized excitations. While evidence of this exotic state has b…

Vilmos Kocsis, David A. S. Kaib, Kira Riedl +9
The Kitaev material -RuCl is among the most prominent candidates to host a quantum spin-liquid state endowed with fractionalized excitations. Recent experimental and theoret…
Modified Curie-Weiss Law for Magnets
Ying Li, Stephen M. Winter, David A. S. Kaib +2
In spin-orbit-coupled magnetic materials, the usually applied Curie-Weiss law can break down. This is due to potentially sharp temperature-dependence of the local magnetic moments.…
