Hypergiant spin polarons photogenerated in ferromagnetic europium chalcogenides
X. Gratens, Yunbo Ou, J. Moodera +2
We find that in the ferromagnetic semiconductor EuS, near its Curie temperature, a single band-edge photon generates a spin polaron (SP), whose magnetic moment approaches 20,000 Bo…
Investigation of spin orbit torque driven dynamics in ferromagnetic heterostructures
Xinran Zhou, Hang Chen, Yu-Sheng Ou +5
We use time-resolved (TR) measurements based on the polar magneto-optical Kerr effect (MOKE) to study the magnetization dynamics excited by spin orbit torques in Py (Permalloy)/Pt…
Broadband Circular Polarization Time-Domain Terahertz Spectroscopy
Evan V. Jasper, T. T. Mai, M. T. Warren +6
Light-matter interactions are key in providing fundamental information about materials. Even in the linear-response regime, the spectroscopic response of a material encodes in it m…
Tuning Spin Dynamics and Localization Near the Metal-Insulator Transition in Fe/GaAs heterostructures
Yu-Sheng Ou, N. J. Harmon, Patrick Odenthal +3
We present a simultaneous investigation of coherent spin dynamics in both localized and itinerant carriers in Fe/GaAs heterostructures using ultrafast and spin-resolved pump-probe…
Exchange-driven spin relaxation in ferromagnet/oxide/semiconductor heterostructures
Yu-Sheng Ou, Yi-Hsin Chiu, N. J. Harmon +6
We investigate electron spin relaxation in GaAs in the proximity of a Fe/MgO layer using spin-resolved optical pump-probe spectroscopy, revealing a strong dependence of the spin re…
