The interplay of magnetic order with the electronic scattering and crystal-field effects in a metallic ferromagnet
Payel Shee, Tanaya Halder, Chia-Jung Yang +9
The interplay between magnetic order, charge dynamics, and crystal field excitations underpins the emergent ground states of rare-earth intermetallics. Using time-domain terahertz…
Missing spectral weight in a heavy-fermion system far above Néel temperature
Jingwen Li, Debankit Priyadarshi, Chia-Jung Yang +6
The competition between the Kondo spin-screening effect and the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in heavy-fermion systems drives the quantum phase transition betwee…
Magnetoelectric phase control at domain-wall-like epitaxial oxide multilayers
Elzbieta Gradauskaite, Chia-Jung Yang, Shovon Pal +2
Ferroelectric domain walls are nanoscale objects that can be created, positioned, and erased on demand. They often embody functional properties that are distinct from the surroundi…
Terahertz crystal electric field transitions in a Kondo-lattice antiferromagnet
Payel Shee, Chia-Jung Yang, Shishir Kumar Pandey +5
Hybridization between the localized f-electrons and the delocalized conduction electrons together with the crystal electric field (CEF) play a determinant role in governing the man…
Kondo coherence versus superradiance in THz radiation-driven heavy-fermion systems
Chia-Jung Yang, Michael Woerner, Oliver Stockert +4
In strongly correlated systems such as heavy-fermion materials, the coherent superposition of localized and mobile spin states leads to the formation of Kondo resonant states, whic…
