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.…
Polaronic transport induced by competing interfacial magnetic order in a LaCaMnO/BiFeO heterostructure
Y. M. Sheu, S. A. Trugman, L. Yan +4
Using ultrafast optical spectroscopy, we show that polaronic behavior associated with interfacial antiferromagnetic order is likely the origin of tunable magnetotransport upon swit…
Coexistence of coupled magnetic phases in epitaxial TbMnO3 films revealed by ultrafast optical spectroscopy
J. Qi, L. Yan, H. D. Zhou +5
Ultrafast optical pump-probe spectroscopy is used to reveal the coexistence of coupled antiferromagnetic/ferroelectric and ferromagnetic orders in multiferroic TbMnO3 films through…
Probing the Interplay between Quantum Charge Fluctuations and Magnetic Ordering in LuFe2O4
J. Lee, S. A. Trugman, C. D. Batista +7
Ferroelectric and ferromagnetic materials possess spontaneous electric and magnetic order, respectively, which can be switched by the corresponding applied electric and magnetic fi…
A modal analysis method to describe weak nonlinear effects in metamaterials
Y. Zeng, D. A. R. Dalvit, J. O'Hara +1
We apply a rigorous eigenmode analysis to study the electromagnetic properties of linear and weakly nonlinear metamaterials. The nonlinear response can be totally described by the…
Induced polarization at a paraelectric/superconducting interface
J. T. Haraldsen, S. A. Trugman, A. V. Balatsky
We examine the modified electronic states at the interface between superconducting and ferro(para)-electric heterostructures. We find that electric polarization and superconduc…
