On the relationship between orbital moment anisotropy, magnetocrystalline anisotropy, and Dzyaloshinskii-Moriya interaction in W/Co/Pt trilayers
Zhendong Chi, Yong-Chang Lau, Vanessa Li Zhang +15
We have studied the Co layer thickness dependences of magnetocrystalline anisotropy (MCA), Dzyaloshinskii-Moriya interaction (DMI), and orbital moment anisotropy (OMA) in W/Co/Pt t…
Giant perpendicular magnetic anisotropy in Ir/Co/Pt multilayers
Yong-Chang Lau, Zhendong Chi, Tomohiro Taniguchi +8
We have studied the magnetic properties of multilayers composed of ferromagnetic metal Co and heavy metals with strong spin orbit coupling (Pt and Ir). Multilayers with symmetric (…
Symmetry of Berry and spin Berry curvatures in ferromagnetic CoPt
Guanxiong Qu, Kohji Nakamura, Masamitsu Hayashi
The intrinsic spin Hall conductivity and the anomalous Hall conductivity of ferromagnetic L1-CoPt are studied using first principle calculations of the spin Berry and Berry cur…
Spin Hall effect from hybridized 3-4 orbitals
Yong-Chang Lau, Hwachol Lee, Kohji Nakamura +1
Electrical manipulation of magnetization by spin-orbit torque (SOT) has shown promise for realizing reliable magnetic memories and oscillators. To date, the generation of transvers…
Electric field modulation of the non-linear areal magnetic anisotropy energy
Yong-Chang Lau, Peng Sheng, Seiji Mitani +2
We study the ferromagnetic layer thickness dependence of the voltage-controlled magnetic anisotropy (VCMA) in gated CoFeB/MgO heterostructures with heavy metal underlayers. When th…
Giant nonreciprocal emission of spin waves in Ta/Py bilayers
Jae Hyun Kwon, Jungbum Yoon, Praveen Deorani +5
Spin waves are propagating disturbances in the magnetization of magnetic materials. One of their interesting properties is the nonreciprocity, exhibiting that their amplitude depen…
