Thermal spin transport in easy-planar -wave altermagnets controlled by magnetic field
Yuliia I. Gusieva, Kostiantyn V. Yershov, Jeroen van den Brink +1
The paper studies how magnons in an easy‑planar d‑wave altermagnet (e.g., NiF₂) acquire a momentum‑dependent magnetic moment, enabling a thermal magnon‑driven spin current that can…
Nonlinear Magnon Magnetic Moment Transport in Triangular-Lattice f-Wave Antialtermagnets
Volodymyr P. Kravchuk, Kostiantyn V. Yershov, Bastián Pradenas +7
We study the spin excitations in the frustrated coplanar 120-degree ground state of the triangular-lattice Heisenberg antiferromagnet and demonstrate that they carry a magnetic mom…
Magnon topology driven by altermagnetism
Subhankar Khatua, Volodymyr P. Kravchuk, Kostiantyn V. Yershov +1
Altermagnets present a class of fully compensated collinear magnetic order, where the two sublattices are not related merely by time-reversal combined with lattice translation or i…
Chiral magnetic excitations and domain textures of g-wave altermagnets
Volodymyr P. Kravchuk, Kostiantyn V. Yershov, Jorge I. Facio +5
Altermagnets (AMs) constitute a novel class of spin-compensated materials in which opposite-spin sublattices are connected by a crystal rotation, causing their electronic iso-energ…
Chiral breakdown engineered by mesoscale Dzyaloshinskii-Moriya interaction in biaxial magnetic nanotubes
Kostiantyn V. Yershov, Svitlana Kondovych, Denis D. Sheka
Curvilinear geometries in magnetic nanostructures provide a unique platform for exploring the interplay of symmetry, topology, and curvature in magnetization dynamics. In this work…
Curvature-induced skyrmion deformation
Artur Bichs, Kostiantyn V. Yershov, Volodymyr P. Kravchuk
Here we perform a systematic analysis of equilibrium solutions for Neel and Bloch skyrmions on a cylindrical shell and demonstrate that both experience curvature-induced deformatio…
