Coexistence and tunability of orbital and spin Hall effects in RuO
Lishu Zhang, Mahmoud Zeer, Dongwook Go +8
Altermagnetic materials, especially RuO, have recently attracted considerable attention for their unique magnetic properties and energy-efficient spintronic applications. Howev…
Giant orbital magnetoresistance in the antiferromagnet CoO driven by dynamic orbital angular momentum interaction
Christin Schmitt, Sachin Krishnia, Edgar Galindez-Ruales +12
Recent predictions of orders of magnitude larger orbital current effects compared to spin currents have attracted significant interest. However, the full potential of giant orbital…
Non-reciprocity in magnon mediated charge-spin-orbital current interconversion
José Omar Ledesma-Martin, Edgar Galindez-Ruales, Sachin Krishnia +9
In magnetic systems, angular momentum is carried by spin and orbital degrees of freedom. Nonlocal devices, comprising heavy-metal nanowires on magnetic insulators like yttrium iron…
Manipulating magnetization by orbital current from a light metal Ti
Dongxing Zheng, Jingkai Xu, Fatimah Alsayafi +16
The orbital Hall effect, which does not rely on the spin-orbit coupling, has recently emerged as a promising mechanism for electrically manipulating magnetization in thin-film ferr…
Weak Ferromagnetism in Altermagnets from Alternating -Tensor Anisotropy
Daegeun Jo, Dongwook Go, Yuriy Mokrousov +3
Altermagnets are magnetic materials with antiferromagnetic spin ordering but exhibit ferromagnetic properties. Understanding the microscopic origin of the latter is a central probl…
Symmetry-controlled orbital Hall effect in IrO
Michael Patton, Dongwook Go, Daniel A. Pharis +7
Recent discovery of orbital currents in several material platforms including light element metals has opened new possibilities for exploring novel transport phenomena and applicati…
