Thermal-magnetic noise measurement of spin-torque effects on ferromagnetic resonance in MgO-based magnetic tunnel junctions
Yongfeng Guan, Jonathan Z. Sun, Xin Jiang +3
Thermal-magnetic noise at ferromagnetic resonance (T-FMR) can be used to measure magnetic perpendicular anisotropy of nanoscale magnetic tunnel junctions (MTJs). For this purpose,…
A compact apparatus for studies of element and phase-resolved ferromagnetic resonance
D. A. Arena, Y. Ding, E. Vescovo +3
We present a compact sample holder equipped with electromagnets and high frequency transmission lines; the sample holder is intended for combined x-ray magnetic circular dichroism…
Weakly Coupled Motion of Individual Layers in Ferromagnetic Resonance
D. A. Arena, E. Vescovo, C. -C. Kao +2
We demonstrate a layer- and time-resolved measurement of ferromagnetic resonance (FMR) in a Ni81Fe19 / Cu / Co93Zr7 trilayer structure. Time-resolved x-ray magnetic circular dichro…
Time-domain measurement of driven ferromagnetic resonance
Y. Guan, W. E. Bailey, E. Vescovo +2
We present a time-resolved measurement of magnetization dynamics during ferromagnetic resonance (FMR) in a single layer of Ni81Fe19. Small-angle (<1 deg.) precession of elemental N…
Dual-frequency ferromagnetic resonance
Yongfeng Guan, William E. Bailey
We describe a new experimental technique to investigate coupling effects between different layers or modes in ferromagnetic resonance (FMR). Dual FMR frequencies are excited (2-8 G…
