Effect of multi-layering and crystal orientation on spin-orbit torque efficiency in Ni/Pt layer stacking
A. Sud, Y. -C. Lau, J. Brierley +2
We study spin-orbit torques (SOTs) in Ni/Pt bi-layers and multi-layers by ferromagnetic resonance (FMR) and harmonic-Hall measurements. The effect of multi-layering and crystal ori…
Magnon-magnon coupling in synthetic ferrimagnets
A. Sud, K. Yamamoto, K. Z. Suzuki +2
Magnetic multilayers with interlayer exchange coupling have been widely studied for both static and dynamic regimes. Their dynamical responses depend on the exchange coupling stren…
Tailoring interfacial effect in multilayers with Dzyaloshinskii-Moriya interaction by helium ion irradiation
A. Sud, S. Tacchi, D. Sagkovits +13
We show a method to control magnetic interfacial effects in multilayers with Dzyaloshinskii-Moriya interaction (DMI) using helium (He) ion irradiation. We report results from…
Growth, strain and spin orbit torques in epitaxial NiMnSb films sputtered on GaAs
N. Zhao, A. Sud, H. Sukegawa +7
We report current-induced spin torques in epitaxial NiMnSb films on a commercially available epi-ready GaAs substrate. The NiMnSb was grown by co-sputtering from three targets usin…
Parity-controlled spin-wave excitations in synthetic antiferromagnets
A. Sud, Y. Koike, S. Iihama +3
We report in this study the current-induced-torque excitation of acoustic and optical modes in Ta/NiFe/Ru/NiFe/Ta synthetic antiferromagnet stacks grown on SiO2/Si substrates. The…
Tunable magnon-magnon coupling in synthetic antiferromagnets
A. Sud, C. W. Zollitsch, A. Kamimaki +5
In this work, we study magnon-magnon coupling in synthetic antiferromagnets (SyAFs) using microwave spectroscopy at room temperature. Two distinct spin-wave modes are clearly obser…
