Coherent spin waves in a maximal entropy phase
Arnau Romaguera, Eugenio Paris, Elizabeth Skoropata +24
In solids, disorder is conventionally regarded as detrimental to coherence. It typically localizes and dampens collective excitations, as exemplified by Anderson localization or th…
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…
A light-induced charge order mode in a metastable cuprate ladder
Hari Padma, Prakash Sharma, Sophia F. R. TenHuisen +17
We report the observation of an emergent charge order mode in the optically-excited cuprate ladder SrCuO. Near-infrared light in the ladder plane drives a symm…
Symmetry-protected electronic metastability in an optically driven cuprate ladder
Hari Padma, Filippo Glerean, Sophia F. R. TenHuisen +23
Optically excited quantum materials exhibit nonequilibrium states with remarkable emergent properties, but these phenomena are usually transient, decaying on picosecond timescales…
Magnetic properties of a highly ordered single crystal of the layered perovskite YBaCuFeMnO
Xiaodong Zhang, Arnau Romaguera, Felip Sandiumenge +4
The layered perovskite YBaCuFeO5 (YBCFO) is able to adopt chiral magnetic order up to unexpectedly high temperatures, paving the way to strong magnetoelectric coupling at room temp…
Tuning the tilting of the spiral plane by Mn doping in YBaCuFeO5 multiferroic
X. Zhang, A. Romaguera, O. Fabelo +3
The layered perovskite YBaCuFeO5 (YBCFO) is considered one of the best candidates to high-temperature chiral multiferroics with strong magnetoelectric coupling. In RBaCuFeO5 perovs…
Ferromagnetic metallic Sr-rich LnACoO cobaltites with spontaneous spin rotation
Jessica Padilla-Pantoja, Arnau Romaguera, Xiaodong Zhang +4
The PrSr0CoO perovskite exhibits unique magnetostructural properties among the rest of ferromagnetic/metallic LnSrCoO compounds. The sudd…
