Design Principles for Quasi-Isotropic Exchange in Rare-Earth Quantum Magnets
Kotaro Shimizu, Esteban Agustin Ghioldi, Filip Ronning +1
Rare-earth quantum materials provide a promising platform for emergent phenomena ranging from quantum spin liquids with long-range entanglement to topological magnetic textures. Ho…
Fabrication of microstructured devices of the unconventional superconductor CeCoIn5 for investigations of isolated grain boundaries
Sanu Mishra, Sean M. Thomas, Rod Mccabe +2
Grain boundaries are critical for determining the functionality of polycrystalline materials. Here we present on the structural transport properties of grain boundaries in the…
Magnetic Field Dependence of the Spin Fluctuations in CeCuAg
X. Boraley, A. D. Christianson, J. Lass +9
Quantum phase transitions are among the most intriguing phenomena that can occur when the electronic ground state of correlated metals are tuned by external parameters such as pres…
Evolution of magnetic bubble domains in the uniaxial ferromagnet CeRuGaB inferred from the Hall effect and ac magnetic susceptibility
Peter E. Siegfried, Mark Maus, Alexander C. Bornstein +6
We study the Hall effect, AC magnetic susceptibility (), and magnetic force microscopy of the uniaxial ferromagnet CeRuGaB with a centrosymmetric crystal struc…
Exploring the apparent violation of the Mott relation in a noncentrosymmetric kagome ferromagnet
Benjamin Kostroun, Tomoya Asaba, Sean M. Thomas +4
In magnetic topological materials, time-reversal symmetry breaking gives rise to topological point and line nodes with distinctive signatures in the anomalous Hall and anomalous Ne…
Evidence for easy-plane XY ferromagnetism in heavy-fermion quantum-critical CeRh6Ge4
Riku Yamamoto, Sejun Park, Zachary W. Riedel +6
We report Ge nuclear quadrupole resonance (NQR) and magnetic resonance (NMR) spectroscopy in the heavy-fermion quantum-critical ferromagnet CeRhGe. NQR and NMR spect…
