Pressure-induced huge increase of Curie temperature of the van der Waals ferromagnet VI3
J. Valenta, M. Kratochvílová, M. Míšek +12
Evolution of magnetism in single crystals of the van der Waals compound VI3 in external pressure up to 7.3 GPa studied by measuring magnetization and ac magnetic susceptibility is…
Nature of the spin resonance mode in CeCoIn
Yu Song, Weiyi Wang, John S. Van Dyke +9
Spin-fluctuation-mediated unconventional superconductivity can emerge at the border of magnetism, featuring a superconducting order parameter that changes sign in momentum space. D…
Neutron Spin Resonance in the Heavily Hole-doped KFeAs Superconductor
Shoudong Shen, Xiaowen Zhang, Hongliang Wo +6
We report high-resolution neutron scattering measurements of the low energy spin fluctuations of KFeAs, the end member of the hole-doped BaKFeAs fam…
Crystal Structures and Phase Transitions of the van-der-Waals Ferromagnet VI3
Petr Doležal, Marie Kratochvílová, Václav Holý +8
The results of a single-crystal X-ray-diffraction study of the evolution of crystal structures of VI3 with temperature with emphasis on phase transitions are presented. Some relate…
Evidence for singular-phonon-induced nematic superconductivity in a topological superconductor candidate SrBiSe
Jinghui Wang, Kejing Ran, Shichao Li +11
Superconductivity mediated by phonons is typically conventional, exhibiting a momentum-independent s-wave pairing function, due to the isotropic interactions between electrons and…
Lattice dynamics and coupled quadrupole-phonon excitations in CeAuAl
B. -Q. Liu, P. Čermák, C. Franz +2
We report first principles calculations of the structural parameters and phonon dispersion of the tetragonal non-centrosymmetric heavy fermion compound CeAuAl. Taking into acco…
Ultra-small moment incommensurate spin density wave order masking a ferromagnetic quantum critical point in NbFe
P. G. Niklowitz, M. Hirschberger, M. Lucas +8
In the metallic magnet NbFe, the low temperature threshold of ferromagnetism can be investigated by varying the Fe excess within a narrow homogeneity range. We…
Robust Upward Dispersion of the Neutron Spin Resonance in the Heavy Fermion Superconductor CeYbCoIn
Yu Song, John Van Dyke, I. K. Lum +10
The neutron spin resonance is a collective magnetic excitation that appears in copper oxide, iron pnictide, and heavy fermion unconventional superconductors. Although the resonance…
Magnetic and structural transitions in LaNaFeAs single crystals
J. -Q. Yan, S. Nandi, B. Saparov +10
LaNaFeAs single crystals have been grown out of an NaAs flux in an alumina crucible and characterized by measuring magnetic susceptibility, electrical resis…
Magnetic structures in the rich magnetic phase diagram of HoRhIn
Petr Čermák, Karel Prokeš, Bachir Ouladdiaf +3
The magnetic phase diagram of the tetragonal HoRhIn compound has similar features to many related systems, revealing a zero magnetic field AF1 and a field-induced AF2 phase…
Magnetic structures of non-cerium analogues of heavy-fermion Ce2RhIn8: case of Nd2RhIn8, Dy2RhIn8 and Er2RhIn8
Petr Čermák, Pavel Javorský, Marie Kratochvílová +5
R2RhIn8 compounds (space group P4/mmm, R is a rare-earth element) belong to a large group of structurally related tetragonal materials which involves several heavy-fermion supercon…
