Dispersive-phonon-driven room-temperature Ni1+-Ni2+ polaron hopping in spin-charge coupled rutile niobate
Gourab Roy, Mohit Kumar, Sayan Ghosh +4
Understanding how lattice dynamics mediate polaron hopping is essential for designing multifunctional correlated oxides. Here, we demonstrate room-temperature dispersive phonon exc…

Microscopic investigation of spin dynamics in the single-chain magnet Sr4Mn2CoO9
G. Roy, S. Ghosh, M. Kumar +8
One-dimensional single-chain magnets offer a unique platform for studying the interplay of crystal-field effects, exchange interactions, and lattice dynamics. Here, we investigate…
