Geometric Spin Rotation in Triangular Antiferromagnets
Grigor Adamyan, Bastian Pradenas, Boris Ivanov +1
We describe a geometric phenomenon in which a traveling wave made of degenerate Goldstone modes leaves behind a transformed ground state. In a triangular Heisenberg antiferromagnet…
Light-driven ultrafast phonomagnetism
D. Afanasiev, J. R. Hortensius, B. A. Ivanov +6
Exciting atomic oscillations with light is a powerful technique to control the electronic properties of materials, leading to remarkable phenomena such as light-induced superconduc…
Dynamics and relaxation in spin nematics
V. G. Bar'yakhtar, V. I. Butrim, A. K. Kolezhuk +1
We study dynamics and relaxation of elementary excitations (magnons) in the spin nematic (quadrupole ordered) phase of S=1 magnets. We develop a general phenomenological theory of…
Vortex ground state for small arrays of magnetic particles with dipole coupling
S. A. Dzian, A. Yu. Galkin, B. A. Ivanov +2
We show that a magnetic vortex is the ground state of an array of magnetic particles shaped as a hexagonal fragment of a triangular lattice, even for an small number of particles i…
Ground states and magnetization process for an triangular lattice array of magnetic dots with perpendicular anisotropy
V. E. Kireev, R. S. Khymyn, B. A. Ivanov +1
We analyzed the ground state of the array of magnetic particles (magnetic dots) which form a two-dimensional triangular lattice, and magnetic moment of which is perpendicular to th…
Pairing of Solitons in Two-Dimensional S=1 Magnets
B. A. Ivanov, R. S. Khymyn, A. K. Kolezhuk
We discuss the structure of topological solitons in a general non-Heisenberg model of isotropic two-dimensional magnet with spin S=1, in the vicinity of a special point where the m…
