Plaid-Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe
Dirk Wulferding, Daehyeon An, Jiwon Choi +8
Altermagnets constitute an emerging class of magnetic materials that combine compensated antiferromagnetic order with spin-split excitations arising from crystalline symmetries. De…
Kineo-Elasticity and Nonreciprocal Phonons by Rashba-induced Interfacial Spin-Lattice Coupling
Gyungchoon Go, Se Kwon Kim
We identify a previously unrecognized spin-lattice coupling that is allowed in the presence of broken inversion symmetry that can be considered as a lattice analogue to the electro…
Unidirectional gliding of a cycloidal spin structure by an AC magnetic field
Dong Hui Han, Kyoung-Woong Moon, Kab-Jin Kim +1
The dynamics of a cycloidal spin structure driven by an AC magnetic field is theoretically studied in the weak-field limit. A specific model Hamiltonian describing the cycloidal sp…
Chiral-split magnons in the S = 1 Shastry-Sutherland model
Absur Khan Siam, Se Kwon Kim
In ferromagnets, magnons have only one chirality; while in common antiferromagnets, bands with opposite chiralities are degenerate across the Brillouin zone. Recent studies have sh…
Colossal enhancement of spin transmission through magnon confinement in an antiferromagnet
Sajid Husain, Maya Ramesh, Xinyan Li +21
Since Felix Bloch's introduction of the concept of spin waves in 1930, magnons (the quanta of spin waves) have been extensively studied in a range of materials for spintronics, par…
Magnon thermal conductivity in multiferroics with spin cycloids
Hyeon Woo Park, Shu Zhang, Peter Meisenheimer +7
Multiferroic materials, characterized by the occurrence of two or more ferroic properties, hold potential in future technological applications and also exhibit intriguing phenomena…
Magnon-induced scalar spin chirality in Kagome and honeycomb ferromagnets
Nanse Esaki, Gyungchoon Go, Se Kwon Kim
The scalar spin chirality (SSC), defined as a triple product of spins, is essential for describing noncoplanar spin structures and understanding chiral physics in magnetic systems.…
Intrinsic Nernst effect of the magnon orbital moment in a honeycomb ferromagnet
Daehyeon An, Se Kwon Kim
The Nernst effect of the magnon orbital moment is theoretically investigated in a honeycomb ferromagnet, whose Hamiltonian contains the Heisenberg exchange, the Dzyaloshinskii-Mori…
Emergence of Meron Kekulé lattices in twisted Néel antiferromagnets
Kyoung-Min Kim, Se Kwon Kim
A Kekulé lattice is an exotic, distorted lattice structure exhibiting alternating bond lengths, distinguished from naturally formed atomic crystals. Despite its evident applicabili…
