Field-tuned quasiparticles and electronic structure in heavy-fermion YbNi 4 ...

Published on 2026-10-09 by Will Broad, Owen Moulding, Takaki Muramatsu, Manuel Brando, Alix McCollam, Femke Bangman, Gertrud Zwicknagl, Kristin Kliemt, Cornelius Krellner and Sven Friedemann @IOP SCIENCE

Abstract: We study the Fermi surface topology and quasiparticle properties of the heavy fermion compound at high magnetic fields using quantum oscillation (QO) measurements. We observe a large decrease of the quasiparticle mass with increasing field and demonstrate good qualitative agreement with the single-ion Kondo model. At the putative Lifshitz transition at 17 T, we observe a sudden change of QO frequencies suggesting an abrupt change of the electronic structure and/or quasiparticle characteristics. [...]

three-temperature approach

Published on 2026-09-29 by A I Bezuglyj and L N Davydov @IOP SCIENCE

Abstract: Within the framework of the phenomenological three-temperature approach, we considered the dynamics of the temperatures of electrons, phonons and magnons in a layered heterostructure consisting of a thin film of normal metal (NM), a layer of ferromagnetic insulator (FI) and a massive dielectric substrate. The dependence of the constant and variable components of the inverse spin Hall effect voltage on the thickness of the FI during periodic heating of the NM was obtained. From the agreement betw[...]
