Ultrafast Polaron Dynamics in Layered and Perovskite Manganites: 2D and 3D Polarons
J. Lee, H. J. Lee, R. D. Averitt +8
We have studied the sub-picosecond quasiparticle dynamics in the perovskite manganite La0.7Ca0.3MnO3 and the layered manganite La1.4Sr1.6Mn2O7 using ultrafast optical spectroscopy.…
Hot electron relaxation in a heavy fermion system with tuned doping
J. Demsar, V. V. Kabanov, A. S. Alexandrov +4
Femtosecond time-resolved optical spectroscopy was used to systematically study photoexcited carrier relaxation dynamics in the intermediate-valence heavy fermion system Yb1-xLuxAl…
Time-Resolved Quasiparticle Dynamics in the Spin-Density-Wave State
Elbert E. M. Chia, Jian-Xin Zhu, H. J. Lee +5
Time-resolved photoinduced reflectivity is measured in the spin-density-wave (SDW) phase using itinerant antiferromagnets UMGa (M=Ni, Pt). For UNiGa [=85 K, =…
Quasiparticle Relaxation Across a Spin Gap in the Itinerant Antiferromagnet UNiGa5
Elbert E. M. Chia, H. J. Lee, Namjung Hur +5
Ultrafast time-resolved photoinduced reflectivity is measured for the itinerant antiferromagnet UNiGa (85 K) from room temperature to 10 K. The relaxation time…
Enhanced Optical Gap in Bi-layered Manganites LaSrMnO near
Myung Whun Kim, H. J. Lee, B. J. Yang +4
We have systematically investigated the optical conductivity spectra of LaSrMnO (). We find that just above the magneti…
Complicated nature of the gap in MgB2: magnetic field-dependent optical studies
H. J. Lee, J. H. Jung, K. W. Kim +7
We investigated the magnetic field (H)-dependent optical conductivity spectra of MgB2 thin film in the far-infrared region. The H-dependences can be explained by the increase of no…
