High-energy magnetic excitations from heavy quasiparticles in CeCuSi
Yu Song, Weiyi Wang, Chongde Cao +8
Magnetic fluctuations is the leading candidate for pairing in cuprate, iron-based and heavy fermion superconductors. This view is challenged by the recent discovery of nodeless sup…
Spin dynamics in NaFeAs and NaFeCuAs probed by resonant inelastic X-ray scattering
Yu Song, Weiyi Wang, Eugenio Paris +11
The parent compounds of iron-based superconductors are magnetically-ordered bad metals, with superconductivity appearing near a putative magnetic quantum critical point. The presen…
Magnetic phase diagram of EuCuSi derived from thermal expansion and magnetostriction studies
Liran Wang, Lars Wallbaum, Changhyun Koo +3
Precise thermal expansion and magnetostriction studies of the intermetallic compound EuCuSi in the temperature range between 5 and 300 K are presented. A clear sign of magn…
NaFeCuAs: A pnictide insulating phase induced by on-site Coulomb interaction
C. E. Matt, N. Xu, B. Q. Lv +13
In the studies of iron-pnictides, a key question is whether their bad-metal state from which the superconductivity emerges lies in close proximity with a magnetically ordered insul…
Distinct itinerant spin-density waves and local-moment antiferromagnetism in an intermetallic ErPdSi single crystal
Hai-Feng Li, Chongde Cao, Andrew Wildes +8
Identifying the nature of magnetism, itinerant or localized, remains a major challenge in condensed-matter science. Purely localized moments appear only in magnetic insulators, whe…
Magnetic anomalies in single crystalline ErPd2Si2
E. V. Sampathkumaran, Niharika Mohapatra, Kartik K Iyer +3
Considering certain interesting features in the previously reported 166Er Moessbauer effect and neutron diffraction data on the polycrystalline form of ErPd2Si2 crystallizing in Th…
