Coupled magnon-phonon excitations in Sr2CuCl2O2 at high pressure
High-pressure optical experiments have been performed on midinfrared excitations unique to the layered cuprates, yet whose physical origin has been unresolved. Measurements of high-pressure midinfrared spectra of Sr2CuCl2o2 unambiguously identify the ;2800-cm 21 absorption as an unusual quasibound two-magnon 1 phonon excitation. We further show that the broad peak centered near ;4000 cm is a fo...

متن کاملMagnon damping by magnon-phonon coupling in manganese perovskites
Inelastic neutron scattering was used to systematically investigate the spin-wave excitations ~magnons! in ferromagnetic manganese perovskites. In spite of the large differences in the Curie temperatures (TC’s! of different manganites, their low-temperature spin waves have very similar dispersions with the zone-boundary magnon softening and broadening that cannot be explained by the canonical d...

متن کاملGrowth mechanism and magnon excitation in NiO nanowalls
The nanosized effects of short-range multimagnon excitation behavior and short-circuit diffusion in NiO nanowalls synthesized using the Ni grid thermal treatment method were observed. The energy dispersive spectroscopy mapping technique was used to characterize the growth mechanism, and confocal Raman scattering was used to probe the antiferromagnetic exchange energy J2 between next-nearest-nei...
