Low magnetic damping of ferrimagnetic GdFeCo alloys
Duck-Ho Kim, Takaya Okuno, Se Kwon Kim +12
We investigate the Gilbert damping parameter for rare earth (RE)-transition metal (TM) ferrimagnets over a wide temperature range. Extracted from the field-driven magnetic domain-w…
Dzyaloshinskii-Moriya interaction induced extrinsic linewidth broadening of ferromagnetic resonance
Jung Hyun Oh, Ik-Sun Hong, Kyung-Jin Lee
For a thin ferromagnetic film with the Dzyaloshinskii-Moriya interaction (DMI), we derive an expression of the extrinsic ferromagnetic resonance (FMR) linewidth in a quantum mechan…
Spin-transfer-torque efficiency enhanced by edge-damage of perpendicular magnetic random access memories
Kyungmi Song, Kyung-Jin Lee
We numerically investigate the effect of magnetic and electrical damages at the edge of a perpendicular magnetic random access memory (MRAM) cell on the spin-transfer-torque (STT)…
Angular dependence of spin-orbit spin transfer torques
Ki-Seung Lee, Dongwook Go, Aurelien Manchon +4
In ferromagnet/heavy metal bilayers, an in-plane current gives rise to spin-orbit spin transfer torque which is usually decomposed into field-like and damping-like torques. For two…
Spin-Wave Propagation in the Presence of Interfacial Dzyaloshinskii-Moriya Interaction
Jung-Hwan Moon, Soo-Man Seo, Kyung-Jin Lee +5
In ferromagnetic thin films, broken inversion symmetry and spin-orbit coupling give rise to interfacial Dzyaloshinskii-Moriya interactions. Analytic expressions for spin-wave prope…
