Imaging Nonlinear Spin Waves in Magnetoacoustic Devices
N. Beaver, B. Luo, S-W. Chiu +9
Magnetoacoustic systems offer promising platforms for next-generation sensors and computing applications, but understanding their nonlinear dynamics remains challenging. Here, we u…
Broadband spintronic detection of the absolute field strength of terahertz electromagnetic pulses
A. L. Chekhov, Y. Behovits, U. Martens +5
We demonstrate detection of broadband intense terahertz electromagnetic pulses by Zeeman-torque sampling (ZTS). Our approach is based on magneto-optic probing of the Zeeman torque…
Terahertz spin conductance probes of coherent and incoherent spin tunneling through MgO tunnel junctions
R. Rouzegar, M. A. Wahada, A. L. Chekhov +9
We study femtosecond spin currents through MgO tunneling barriers in CoFeB(2 nm)|MgO()|Pt(2 nm) stacks by terahertz emission spectroscopy. To obtain transport information indepe…
Symmetry and nonlinearity of spin wave resonance excited by focused surface acoustic waves
Piyush J. Shah, Derek A. Bas, Abbass Hamadeh +6
The use of a complex ferromagnetic system to manipulate GHz surface acoustic waves is a rich current topic under investigation, but the high-power nonlinear regime is under-explore…
Ferromagnetic dynamics detected via one- and two-magnon NV relaxometry
Brendan A. McCullian, Ahmed M. Thabt, Benjamin A. Gray +7
The NV center in diamond has proven to be a powerful tool for locally characterizing the magnetic response of microwave excited ferromagnets. To date, this has been limited by the…
