Oxygen-isotope effect on density wave transitions in LaNiO
Rustem Khasanov, Vahid Sazgari, Igor Plokhikh +11
TThe isotope effect is a powerful probe of electron-phonon interactions in solid-state systems, offering key insights into how atomic mass influences emergent quantum states. Here,…
Hierarchical quasiparticle dynamics in antiferromagnets revealed by time- and momentum-resolved X-ray scattering
Arnau Romaguera, Elizabeth Skoropata, Yun Yen +18
Energy flows among coupled subsystems are essential for ultrafast dynamics and high-speed technologies. In magnetic materials, spin fluctuations -- magnons -- mediate these flows i…
Coexistence of insulator-like paramagnon and metallic spin-orbit exciton modes in SrIrO
Eugenio Paris, Wenliang Zhang, Yi Tseng +13
We probe the spectrum of elementary excitations in SrIrO by using heterostructured [(SrIrO)/(SrTiO)] samples to approach the bulk limit. Our resonant inelastic…
Bullet pressure-cell design for neutron scattering experiments with horizontal magnetic fields and dilution temperatures
Ellen Fogh, Gaétan Giriat, Richard Gaal +10
The simultaneous application of high magnetic fields and high pressures for controlling magnetic ground states is important for testing our understanding of many-body quantum theor…
Competition Between Multiferroic and Magnetic Soliton Lattice States in DyFeO
S. E. Nikitin, N. D. Andriushin, Ã. S. FjellvÃ¥g +5
Simultaneous breaking of time reversal and inversion symmetries in multiferroics couples ferroelectricity to magnetism and is a source of unusual physical phenomena that can be use…
