Using ultrashort optical pulses to couple ferroelectric and ferromagnetic order in an oxide heterostructure
Y. M. Sheu, S. A. Trugman, L. Yan +3
A new approach to all-optical detection and control of the coupling between electric and magnetic order on ultrafast timescales is achieved using time-resolved second harmonic gene…

Photo-induced stabilization and enhancement of the ferroelectric polarization in BaSrTiO/LaCa(Sr)MnO thin film heterostructures
Y. M. Sheu, S. A. Trugman, L. Yan +5
An emerging area in condensed matter physics is the use of multilayered heterostructures to enhance ferroelectricity in complex oxides. Here, we demonstrate that optically pumping…

Ultrafast carrier dynamics and radiative recombination in multiferroic BiFeO
Y. M. Sheu, S. A. Trugman, Y. -S. Park +6
We report a comprehensive study of ultrafast carrier dynamics in single crystals of multiferroic BiFeO. Using femtosecond optical pump-probe spectroscopy, we find that the ph…
