Observation of current-induced orbital quadrupole accumulation

Geun-Hee Lee, Yubin Ji, Yongho Park +12

Spintronics and orbitronics rely on current-induced accumulations of magnetic dipoles: spin and orbital angular momentum. However, electronic orbitals inherently carry multipoles b…

Magnetic Octupole Hall Effect in d-Wave Altermagnets

Hye-Won Ko, Kyung-Jin Lee

Order parameters not only characterize symmetry-broken equilibrium phases but also govern transport phenomena in the nonequilibrium regime. Altermagnets, a class of magnetic system…

Orbital Pumping Incorporating Both Orbital Angular Momentum and Position

Seungyun Han, Hye-Won Ko, Jung Hyun Oh +3

We develop a theory of adiabatic orbital pumping, highlighting qualitative differences from spin pumping. An oscillating magnetic field pumps not only orbital angular momentum curr…

Identifying intrinsic and extrinsic mechanisms of anisotropic magnetoresistance with terahertz probes

Ji-Ho Park, Hye-Won Ko, Jeong-Mok Kim +7

Identifying the intrinsic and extrinsic origins of magneto-transport in spin-orbit coupled systems has long been a central theme in condensed matter physics. However, it has been e…

Role of orbital hybridization in anisotropic magnetoresistance

Hye-Won Ko, Hyeon-Jong Park, Gyungchoon Go +3

We theoretically and numerically show that longitudinal orbital currents in ferromagnets depend on the magnetization direction, which contribute to the anisotropic magnetoresistanc…
